▼ Discovery of high-temperature superconductors aroused a great interest in studies on these materials. In 1987 an yttrium-based compound YBCO (Yttrium-Barium- Copper-Oxide) was synthesised with Tc at 93 K. It was immediately evident that the BCS theory does not explain the pairing mechanism in these oxide-based superconductors, which predicted that a maximum Tc of about 30 K could be achieved. Layered copper oxides were for a long time the most studied high-Tc superconductors. With the discovery, at the beginning of 2008, by Kamihara of a new non-cuprate high-Tc superconductor a different path of studies had opened. This family of quaternary oxyarsenides LaO1-xFxFeAs was surprising due to the presence of Fe, which should lead to long-range magnetic order suppressing superconductivity. Although the parent compound LaFeAsO is not superconducting, electron doping (by partial substitution of O2- with F-) leads to superconductivity with Tc of 26 K. Since these discoveries there has been extensive research on the family of rare-earth quaternary oxypnictides with general formula REFaAsO (RE = La, Sm, Ce, Nd, Pr, Gd, Tb, Dy) and with Tc reaching 55 K for electron doped SmFeAsO. A study of new NdFeAsO family with Sr doping on Nd site was conducted. Synthesis of Nd1-xSrxFeAsO compounds and their further characterisation revealed that hole doping in these materials is a successful route to achieve superconductivity. Partial substitution of Nd3+ by Sr2+ with small doping level (x = 0.05) shows semiconducting type behaviour, while increasing doping level leads to the emergence of metallic conductivity and with level of doping 20% obtaining superconductivity at Tc = 13.5 K. These materials adopt a simple tetragonal crystal structure (space group P4/nmm), which undergoes a structural phase transition on cooling to orthorhombic symmetry (space group Cmma). The changes of structural, electronic and magnetic properties with doping level show very different behaviour – non-symmetric to the electron doped side of the phase diagram. The family of Fe-As based superconductors has expanded further by the discoveries of A1-xA’xFe2As2 (A = Alkaline Earth, A’ = Alkali metal), LiFeAs and NaFeAs phases, Sr3Sc2Fe2As2O5. A series of iron-based oxyarsenides with general formula Sr4M12O6M2 2As2 (M1 = Sc, Cr, V; M2 = Fe, Co, Ni) was synthesised and their structure was studied using powder X-ray and neutron diffraction. These materials adopt tetragonal crystal structure (space group P4/nmm) in analogy with REFeAsO systems. The Fe-As planes are sandwiched between perovskite K2NiF4-type oxide layers of Sr4M2O6 (MI = Sc, Cr, V), the large size of which creates a large distance between Fe-As planes. In spite of structural analogy with REFeAsO these new materials show a different behaviour from REFeAsO, which is absence of a structural phase transition on cooling. Both Sr4V2O6Fe2As2 and Sr4Sc2O6Ni2As2 compounds are superconducting without doping with Tc at 28 K and 2.5 K respectively. Neither Sr4Sc2O6Fe2As2 nor Sr4Cr2O6Fe2As2 show these properties, but are…

▼ The current development technique for Bi-2212 multifilament superconducting wire is the oxide powder in tube process. For this process, phase pure Bi-2212 fine powder is loaded into a silver tube then drawn, stacked, and redrawn until the desired filament size and number is achieved. The wire is then cabled and wound onto its final form where it undergoes a partial melt heat treatment in an overpressure environment of 5 -10 MPa. The entire form is cooled in a controlled way to allow the liquid to recrystallize into phase pure Bi-2212. However, the partial melt heat treatment process leads to several difficulties. Small void spaces within the initial powder can coalesce into large bubbles after the heat treatment. These large bubbles can occlude any supercurrent from traveling along the filament. The melt liquid is also chemically aggressive and will etch and therefore weaken the silver matrix. Lastly, the recrystallized Bi-2212 is not textured and there is limited connectivity between individual crystal formations. Each of these difficulties need to be addressed simultaneously to optimize the performance of future Bi-2212 superconducting wires. A new method for preparing Bi-2212 multifilament wires is being developed to minimize the effects of the above mentioned difficulties. Fine Bi-2212 powder is homogenously mixed with nano-scale silver powder and uniaxially compressed into square cross section bars. The bars are loaded into a silver tube then drawn, stacked, and redrawn until the desired filament size and number is achieved. To avoid the complications of the partial melt heat treatment a non-melt heat treatment was developed. The non-melt heat treatment takes advantage of the material properties of the Bi-2212/silver interface. The bulk of the Bi-2212 is never melted, but interconnectivity and grain growth is still achieved. The cores used to fabricate the multifilament wires display significant superconductivity in liquid nitrogen, but the multifilament wires show no signs of superconductivity. Separate optimization of the wires in liquid helium is required to maximum the supercurrent carrying potential of the multifilament wires. Additional study on oxygen doping during the non-melt heat treatment may also be necessary.

▼ The nematic phase transition in Fe-based superconductors (FeSCs) has been a topic under intensive investigation. So far it is commonly accepted that the structural transition from tetragonal (C4) to orthorhombic (C2) symmetry in FeSCs has an electronic nematic origin due to the unusual anisotropy in resistivity, optical conductivity and orbital occupancy observed above the structural transition. However, recent studies of (Ba, Eu)Fe2(As1-xPx)2 by magnetic torque measurements show the existence of a “true” nematic transition well above the commonly accepted structural/nematic transition .Controversies about this “true” nematic phase transition arise as residue strains or external applied fields are known to break C4 symmetry and render the structural transition merely a crossover. We performed high resolution AC micro-calorimetry and SQUID magnetometry measurements of BaFe2(As1-xPx)2 (x=0, 0.3) to investigate the various phase transitions and to explore the “true” nematic phase transition. The advantageous design of our membrane calorimeter allows us to perform high resolution studies of the thermodynamic phase transitions without any symmetry breaking fields. Our results suggest that there is not a second order “true” nematic phase transition in BaFe2(As1-xPx)2 even though the Ginzburg-Landau model used to fit the magnetic torque data indicates that the expected thermal anomaly should be within our experimental resolution. In addition to the above, we present specific heat and magnetization studies of Ba1-xNaxFe2As2 in search of the recent discovered emergent reentrant C2 to C4 symmetry SDW transition in this series of compound. Our results indeed locate a new phase transition in Ba0.74Na0.26Fe2As2 at 45K. However, the absence of the conventional SDW transition at around 80K in our data leaves doubt about the exact nature of this new phase transition. We also systematically studied the effects of heavy ion irradiation (HII) on the anisotropy of YBCO single crystals by angular rotation specific heat measurements. We found that the anisotropy of YBCO decreases by approximately a factor of two with an irradiation dose of 6T (matching field). The dependence of anisotropy on irradiation doses agrees well with the prediction from a simple phenomenological model that takes into account the anisotropic scattering caused by columnar defects created in HII.

▼ Superconducting wires based on the high field superconductor Bi_(2)Sr_(2)Ca_(1)Cu_(2)O_(8)+x are an enabling technology for the development of very high field (>18 T) magnets. While these conductors have the potential to serve as the conductors for magnets operating in excess of 45 T, the achieved current carrying capacity of these materials is too low for economical implementation in high field operation. This is in part due to low density of the superconductors within the cores, the presence of current occluding non-superconducting phases, and a non-optimum alignment of the superconducting particles that form the conductor. The body of work reported in this dissertation aims to develop methods to align (texture) the superconducting particles within the conductors, to enhance the density of the superconducting filaments, to examine a heat treatment that does not form parasitic phases, and to demonstrate that long lengths of superconducting wire can be fabricated with these properties. Three general experimental thrusts are carried out within the work. First, methods for texturing Bi-2212 loose powders were developed and the products of these developments were characterized via x-ray diffraction and microscopy to qualify the degree of imparted texture. The second thrust focused on the development of a monocore wire based on a high density textured Bi-2212 precursor. Multiple wires were extruded and drawn through traditional processes and the products were characterized microscopically to ascertain the quality of the products. The third and final thrust was the development of a non-melt heat treatment that was shown to grow grains of Bi-2212 powder and densify composites. Measurements of the transport critical currents for the heat treated conductors were carried out in boiling liquid helium and background magnetic fields of up to 5 T. These results were correlated to microstructural observations. Ultimately, it was found that the connections between grains in the sintered conductors were insufficient to allow robust transport current and only 1% of the predicted transport currents were reached through the sintering study.

▼ The energy gap is the most fundamental property of a superconductor. Electron tunneling spectroscopy and point contact spectroscopy (PCS) are powerful techniques for studying the density of states and energy gap features of superconductors. Two different superconducting systems, multiband superconductor MgB2 and proximity induced topological superconductor NbSe2/Bi2Se3 heterostructures were studied using either quasiparticle tunneling in planar tunnel junctions or PCS in this work. MgB2 is a conventional s-wave superconductor originated from electron-phonon interaction with a transition temperature of 39 K, the highest among conventional superconductors. It is also the first well established two-band superconductor. The two different superconducting gaps are caused by the electron-phonon interactions in two weakly interacting bands. Previous research in the group has established a method to fabricate high quality MgB2/native oxide/superconductor planar tunnel junctions and revealed a distribution of gap values in MgB2 from the quasiparticle tunneling spectra. Those results confirmed the importance of the anisotropic electron-phonon interaction. In this thesis, the effect of electron scattering in the tunnel junctions, either from the MgB2 film or the junction interface or barrier, are studied. The scattering was shown to smear out the gap distribution structures in the tunneling spectra. Deterioration of the MgB2 film surface was also found to cause an increase in the π gap value, likely due to an enhancement of interband scattering. In addition, the native oxide barrier composition and properties were obtained from the tunneling spectra. Another novel superconducting system, topological superconductor NbSe2/Bi2Se3 heterostructures were studied using the point contact Andreev reflection (PCAR) spectroscopy method at low temperatures down to 40 mK. According to theories, when the 3D topological insulator Bi2Se3 surface state is in proximity with an s-wave superconductor NbSe2, the resulting superconducting surface state resembles the spinless topological superconductor, which is predicted to host Majorana fermions. Scanning Tunneling Spectroscopy (STS) measurements first demonstrated an induced superconducting energy gap in topological insulator Bi2Se3 and Bi2Te3 in the NbSe2/Bi2Se3 and NbSe2/Bi2Te3 heterostructures. In this thesis, PCAR spectra revealed an induced energy gap in the bulk of Bi2Se3 due to the superconducting proximity effect from NbSe2. The gap values were consistent with the bulk superconducting gap observed by the ARPES and STS measurements. The gap was ~0.16 meV at low temperature in a NbSe2/16QL Bi2Se3 heterostructure. In addition, below 0.45 K, a plausible second energy gap ~0.12 meV appeared in the NbSe2/16QL Bi2Se3 PCAR spectra which could indicate a superconducting gap in the topological surface state. Besides spectroscopic measurements on superconducting energy gap features, a study of high-field properties of carbon-doped MgB2 superconducting thin films prepared by hybrid physical-chemical…

▼ High Temperature Superconductors (HTSCs) were rst discovered in 1986, but despite enormous amount of research for last two decades, these materials are still not yet completely understood. HTSCs exhibit very complicated three dimensional phase diagram parameterized by temperature, magnetic led and carrier concentration. Up to now we do not know how to properly characterize all of their di erent phases, in particular the so-called pseudogap (PG) phase where the system is not macroscopically a superconductor but shows properties similar to the superconducting (SC) state. Angle Resolved Photoemission Spectroscopy (ARPES) that probes the momentum space structure of a system has greatly contributed to our understanding of the electronic structure of HTSCs. In this thesis I will present various ARPES studies on HTSCs. In order to understand the origin of high temperature superconductivity in copper ox- ides, we must understand the normal state from which it emerges. I will present the evolu- tion of the normal state electronic excitations with temperature and carrier concentration in Bi2Sr2CaCu2O8+ using ARPES data. I will show that unlike conventional superconductor, the high temperature superconductors exhibit two additional temperature scales which are pseudo- gap scale T , below which electronic excitations exhibit an energy gap, coherence scale Tcoh, below which sharp spectral features appear due to increased lifetime of the excitations. And T and Tcoh are strongly doping dependent, and cross each other near optimal doping. I will also present ARPES observation of the electronic excitations of the non-superconducting state that exists between the antiferromagnetic Mott insulator at zero doping and the super- conducting state at larger dopings in Bi2Sr2CaCu2O8+ (Bi2212). I will show that the state is a nodal liquid whose excitation gap becomes zero only at points in momentum space, and the material has the same gap structure as the d-wave superconductor despite that it has resistivity characteristic of an insulator and the absence of coherent quasiparticle peaks. And there is a smooth evolution of the spectrum across the insulator-to-superconductor transition At the end I will show our scaling analysis of ARPES data across the phase diagram. From the scaling analysis, we nd that there is a 2-D scaling relation in the pseudogap phase, but not in the normal states in the over-doped phase. Thus the states in the pseudogap phase share the same properties that are di erent from over-doped phase. And also because of the scaling relation, there is quantum critical line along the Fermi-surface in the pseudogap phase. Advisors/Committee Members: Campuzano, Juan C (advisor).

▼ In this thesis, the growth of c-axis oriented Sr2RuO4 thin films using pulsed laser deposition and their electrical transport properties are systematically discussed. The deposition and optimization process involved several progressive steps. Specifically, the first focus was on the Sr2RuO4 phase optimization in films grown on lattice-matched (LaAlO3)0.3(SrAl0.5Ta0.5O3)0.7 (LSAT) substrates. Film composition was found to be greatly influenced by changes in oxygen pressure, substrate temperature, target to substrate distance, and laser fluence. High oxygen pressure, low substrate temperature, large target to substrate distance, and high laser fluence increased the tendency to form the Ru-rich SrRuO3 phase in the film. The second focus was on improving the electrical transport properties of Sr2RuO4 from metal-insulating to fully metallic and eventually to superconducting behavior. It was observed that the full width at half maximum (FWHM) of the Sr2RuO4 (006) rocking curves in x-ray diffraction (XRD) scan was related to the quality of the electrical transport response. By fine tuning the deposition parameters to obtain low FWHM values, the electrical transport behavior of the Sr2RuO4 thin films was consistently improved from metal-insulating to fully metallic. In addition, localized superconductivity with enhanced superconducting transition temperature Tc onset was also observed among the fully metallic film. An in-depth study of the XRD results in fully metallic films indicated the existence of defects (intergrowths) along the c-axis direction, which caused localized c-axis tensile strain. The existence of structural defects within the film was likely to be responsible for the fact that only localized superconductivity was observed in the films. Furthermore, the enhanced superconducting transition temperature (Tc) relative to bulk single crystals is likely to be associated to localized strain in the film. Finally, Nb doped SrTiO3 substrates were used to achieve better quality growth of partial superconducting Sr2RuO4 thin films. Sr2RuO4 films grown on Nb doped SrTiO3 substrates had smaller FWHM values and lower level of c-axis tensile strain compared to those on LSAT substrates. Various partially superconducting films with different thicknesses and different superconducting Tc values are presented, and correlations between fabrication process, film crystalline quality as well as transport properties are discussed. This work provides better understanding of the importance of maximizing crystalline quality by delicate fine tuning of PLD deposition parameters to achieve high quality superconducting films.

▼ In this thesis, we present a theoretical investigation of the proximity effects in ferromagnet/superconductor heterostructures with inhomogeneous magnetization, including ferromagnet/ferromagnet/superconductor (F₁F₂S) trilayers and conical-ferromagnet/superconductor bilayers. We numerically obtain the self-consistent solutions of the Bogoliubov-de Gennes (BdG) equations and use these solutions to compute the relevant physical quantities. In F₁F₂S trilayers, we find that the critical temperature, T_c, can be a non-monotonic function of the angle &alpha between magnetizations in F layers. The minimum T_c(&alpha) often occurs when magnetizations are mutually perpendicular (&alpha=&pi/2). In addition, we demonstrate that the T_c minimum corresponds to the maximum of the penetration of the long-range triplet amplitudes. We compare our theoretical results with experiment and find that they are in excellent agreement. We also study other aspects of proximity effects such as the local density of states, local magnetizations, and thermodynamic functions. In conical-ferromagnet/superconductor bilayers, we obtain the relation between T_c and the thickness d_F of the magnetic layer, and find that the T_c(d_F) curves include multiple oscillations. Moreover, for a range of d_F, the superconductivity is reentrant with temperature T: as one lowers T the system turns superconducting, and when T is further lowered it returns to normal. We demonstrate that the behavior of both m=0 and m=±1 triplet amplitudes are related to the intrinsic periodicity of conical ferromagnet. Our theoretical fits of T_c(d_F) are in good agreement with experimental data. The transport properties, including the tunneling conductance and the spin polarized transport, in F₁F₂S trilayers are investigated. To fully take into account proximity effects, we adopt a transfer matrix method incorporated with the Blonder-Tinkham-Klapwijk formalism and self-consistent solutions to the BdG equations. We show that our method ensures that conservation laws are properly satisfied. Our results indicate that the behavior of tunneling conductance depends on the misorientation angle between magnetizations, and also exhibits resonance effects. We also investigate the bias dependence of non-equilibrium spin transfer torque and its connection to both spin currents and local magnetizations.

▼ Quantum computing is a very interesting field, due to the ability of quantum computers to solve many problems much faster than a classical computer. Superconducting qubits are electronic circuits composed of superconducting capacitors, inductors and Josephson junctions, which can implement a physical qubit. However they need improvements in their coherence time to create a viable quantum computing. In this work I study the effect on decoherence caused by two level systems in the native oxide that forms on the surface of qubit. To this end I fabricate 3D transmon qubits using materials grown my molecular beam epitaxy, to which a variety of different surface treatments had been applied. I began by fabricating qubits from niobium/aluminum oxide/niobium trilayers. To this end I developed a self-aligned process for fabricating sub-micron Josephson junctions. This process presented many challenges. During the development of this process, it became clear that niobium was an inferior material for fabricating qubits compared to aluminum. I then switched to making qubits from Aluminum. I began by studying the growth of aluminum on sapphire, and was able to achieve aluminum films with an RMS roughness of 0.2 nm by growing on c-plane sapphire that had been annealed in oxygen at 1100 °C and dipped in BOE. Next I fabricated 3D transmon qubits by adapting the standard shadowmask process for use with MBE. I fabricated qubits with a long in situ oxidation to fully passivate the surface before exposure to air. I also passivated the surface by means of growing co deposited aluminum oxide, and by grown aluminum nitride using a nitrogen plasma source. The coherence times of these qubits were compared to those a control sample that had been exposed to air immediately after growth. Overall it doesn’t appear that cladding the surface changes the coherence time much, however it is difficult to form conclusions with this small sample size. The coated samples appeared to have slightly longer coherence times than the untreated samples, with diffusive oxidation and coating with aluminum oxide providing the largest increase in T1 and diffusive oxidation providing the largest increase in T2.

▼ In searching for novel optimal superconductors, three strategic routes based on theoretical and experimental knowledge from the known high-Tc superconductors are followed. CaFe4As3 is a newly discovered 3D compound, with Fe2+ in tetrahedral coordination, similar to that in the parent compounds of the known superconductors. The thermodynamic and transport properties reveal a spin density wave (SDW) transition at TN = 88 K, and an incommensurate-to-commensurate SDW transition at T2=26.4 K. A large electronic specific heat coefficient γ=0.02 J/molK² and an unusually high Kadowaki-Woods (KW) ratio A/γ²=55×10E−5 μΩcm mol^2K²/mJ² point to strong electron correlations. While the commensurate SDW state below T2 is suppressed in Co-doped CaFe4As3, neither doping with P, Yb, Co and Cu, nor application of hydrostatic pressures up to 5 GPa, is able to fully suppress the robust incommensurate SDW order in this system. The new layered compound SrMnBi2 has been studied as a promising candidate for high Tc superconductivity as suggested by theoretical calculations. We found that SrMnBi2 is structurally similar to, but more two dimensional than the known Fe superconductors. Two phase transitions at T1=292 K and T2=252 K have been observed. A large electronic specific heat coefficient γ=36.5 mJ/molK² and a KW ratio of 9.38×10E−5 μΩcm mol^2K²/mJ² indicate enhanced electron correlations. DFT calculations have revealed metallic Sr-Bi layers in SrMnBi2, as well as Dirac-cone like features in the band structure. Doping experiments on the Mott insulator Sr2F2Fe2OS2 have been carried out to search for superconductivity at the localized-to-itinerant moment crossover. Increasing amounts of T=Mn in Sr2F2(Fe1−xTx)2OS2 suppress the long range magnetic ordering at x≈0.2, and the subsequent increase in x results in a spin glass behavior for 0.2≤x≤0.5, and possibly a new magnetic order for x≥0.5. By contrast, Co-doping increases the AFM transition from TN=106 K for x=0 up to 124 K for x=0.3. The excitation gap determined from the electrical resistivity is minimized but remains finite around x=0.5 for T=Mn. In addition, a study has been done on a rare binary type I superconductor YbSb2. Besides the superconducting transition at Tc=1.30 K, a possible second superconducting phase is observed below Tc(2)=0.41 K. From thermodynamic and transport measurements, there is strong, unambiguous evidence for the type I nature of the superconductivity in YbSb2.

Physics

This thesis has two major topics: (1) Electrostatic Separation of Superconducting Particles from a Mixture of Non-Superconducting Particles. (2) Improvement in fuel atomization by Electrorheology. (1) Based on the basic science research, the interactions between electric field and superconductors, we have developed a new technology, which can separate superconducting granular particles from their mixture with non-superconducting particles. The electric-field induced formation of superconducting balls is important aspect of the interaction between superconducting particles and electric field. When the applied electric field exceeds a critical value, the induced positive surface energy on the superconducting particles forces them to aggregate into balls or cling to the electrodes. In fabrication of superconducting materials, especially HTSC materials, it is common to come across materials with multiple phases: some grains are in superconducting state while the others are not. Our technology is proven to be very useful in separating superconducting grains from the rest non-superconducting materials. To separate superconducting particles from normal conducting particles, we apply a suitable strong electric field. The superconducting particles cling to the electrodes, while normal conducting particles bounce between the electrodes. The superconducting particles could then be collected from the electrodes. To separate superconducting particles from insulating ones, we apply a moderate electric field to force insulating particles to the electrodes to form short chains while the superconducting particles are collected from the middle of capacitor. The importance of this technology is evidenced by the unsuccessful efforts to utilize the Meissner effect to separate superconducting particles from non-superconducting ones. Because the Meissner effect is proportional to the particle volume, it has been found that the Meissner effect is not useful when the superconducting particles are smaller than 45pm. One always come across multi-phase superconducting materials where most superconducting grains are much smaller than 45μm. On the other hand, since our technology is based on the surface effect, it gets stronger when the particles become smaller. Our technology is thus perfect for small superconducting particles and for fabrication of HTSC materials. The area of superconductivity is expected to be very important for 21st Century energy industry. The key for this development is the HTSC materials. We, therefore, expect that our technology will have strong impact in the area. (2) Improving engine efficiency and reducing pollutant emissions are extremely important. Here we report our fuel injection technology based on new physics principle that proper application of electrorheology can reduce the viscosity of petroleum fuels. A small device is thus introduced just before the fuel injection for the engine, producing a strong electric field to reduce the fuel viscosity, resulting in much smaller fuel droplets in…
