▼ This thesis describes a series of experiments and a theoretical study in order to understand and control the behavior of electrons in many-body systems. In particular, the experiments concentrate on competition between the - antagonistic - electronic states of superconductivity and ferromagnetism, and are strongly motivated by the recent proposal of a new type of superconductivity which appears to defy the Pauli principle, if defined in the usual sense. As the central ingredient of our experiments, we use high-quality thin films of half-metallic Chromiumdioxide (or CrO2), best known for its large scale application in the magnetic recording industry, with an experimentally verified close to 100% spin-polarization. We start the experiments with a magnetotransport study of the magnetic properties of these films, and find a Planar Hall effect which demonstrates that the films, which are ordinarily supposed to have a single easy axis in the plane of the film, instead possess a biaxial magnetic anisotropy, which is analyzed in detail. We then contact the CrO2 films to a conventional (s-wave singlet) superconductor, using microfabrication techniques, and show that superconducting correlations originating in the superconductor, enter the CrO2 and persist over distances incompatible with spin singlet and ballistic transport, thereby providing strong evidence for the presence of s-wave triplet correlations. Moreover, from an application point of view, we show that the superconductor-half-metal-superconductor devices we have used to measure this effect are superconducting transistors that can be switched "on" and "off" with the magnetic field. The theoretical part focusses on the influence of voltages, rather than currents or temperature, on the collapse of the superconducting state in a short mesoscopic superconducting wire between normal metal contacts. It is shown that the collapse of the superconducting state is driven by the applied voltage, and not by the resulting current Advisors/Committee Members: Klapwijk, T.M..

The discovery of topological semimetals has attracted enormous interest since they not only possess many unusual exotic properties, but also offer a fertile ground for searching for new fermions in the low energy spectrum. The first established example of a topological state of matter is the quantum Hall effect, which supports a gapless edge state protected by topological invariance. Later the concept of topology has been extended to describe electronic band structure of solid state materials and this effort leads to discoveries of many new topological quantum states, such as Dirac cone state in graphene, quantum spin Hall insulator states in semiconductor quantum wells, 3D topological insulators, etc. The recently discovered Dirac/Weyl semimetals can be viewed as a 3D analog of graphene. This thesis work aims to discover new Dirac/Weyl semimetals through single crystal synthesis and characterization. This thesis is organized as follows: In chapter 1, I will first briefly review several basic concepts of topological properties and introduce a few prototype topological semimetals related to my thesis work. Since one important part of my thesis work involves single crystal growth of topological semimetals, I will introduce the crystal growth methods used in my research in chapter 2. In chapters 3, 4 and 5, I will present my experimental discoveries of new topological semimetals, including YSn2, CaSn3 and TbPtBi. I will not only show property characterization of these material, but also discuss their underlying physics. For YSn2, my work reveals that its slightly distorted square lattice of Sn generates multiple topologically non-trivial bands, one of which likely hosts nodal line and tunable Weyl semimetal state induced by the Rashba spin-orbit coupling (SOC) and proper external magnetic field. The quasiparticles described as relativistic fermions from these bands are manifested by nearly zero mass, and non-trivial Berry phases probed in de Haas–van Alphen (dHvA) oscillations. The dHvA study also reveals YSn2 has a complex Fermi surface (FS), consisting of several 3D and one 2D pocket. Our first principle calculations show the point-like 3D pocket at Y point on the Brillouin zone boundary hosts the possible Weyl state. Our findings establish YSn2 as a new interesting platform for observing novel topological phases and studying their underlying physics. In the study of CaSn3, we not only found it possesses non-trivial band topology, but also discovered its intrinsic superconductivity at 1.178 K. Its topological fermion properties, including the nearly zero quasi-particle mass and the non-trivial Berry phase accumulated in cyclotron motions, were revealed from the dHvA quantum oscillation studies of this material. Our findings make CaSn3 a promising candidate for exploring new exotic states arising from the interplay between non-trivial band topology and superconductivity, e.g., topological superconductivity. For the Half-Heusler compound TbPtBi, we have studied its field-induced Weyl…

▼ This thesis consist of two parts, each of which consist of two chapters. First we explore the information geometric properties of least squares data fitting, particularly for so-called "sloppy" models. Second we describe a calculation of the superconducting superheating field, relevant for advancing gradients in particle accelerator resonance cavities. Parameter estimation by nonlinear least squares minimization is a ubiquitous problem that has an elegant geometric interpretation: all possible parameter values induce a manifold embedded within the space of data. The minimization problem is then to find the point on the manifold closest to the data. By interpreting nonlinear models as a generalized interpolation scheme, we find that the manifolds of many models, known as sloppy models, have boundaries and that their widths form a hierarchy. We describe this universal structure as a hyper-ribbon. The hyper-ribbon structure explains many of the difficulties associated with fitting nonlinear models and suggests improvements to standard algorithms. We add a "geodesic acceleration" correction to the standard Levenberg-Marquardt algorithm and observe a dramatic increase in success rate and convergence speed on many fitting problems. We study the superheating field of a bulk superconductor within the GinzburgLandau, which is valid only near Tc , and Eilenberger theory, which is valid at all temperatures. We calculate as functions of both the Ginzburg-Landau parameter [kappa] and reduced temperature t = T /Tc the superheating field Hsh and the critical momentum kc describing the wavelength of the unstable perturbations to flux penetration. By mapping the two-dimensional linear stability theory into a one-dimensional eigenfunction problem for a linear operator, we solve the problem numerically. Within the Ginzburg-Landau theory, We demonstrate agreement between the numerics and analytics, and show convergence to the known results at both small and large [kappa]. Within the Eilenberger theory we demonstrate agreement with the results of Ginzburg-Landau theory near Tc , but find discrepancies with the temperature-dependent results for large [kappa]. We speculate that this discrepancy is due to a lack of convergence at low temperatures due to small length scales of the perturbations analogous to the small length scales associated with the vortex cores of the mixed state.

▼ The high-temperature superconductivity has remained one of the most puzzling phenomena in contemporary condensed matter physics since its discovery in 1986. Despite enormous quantity of experimental results and theoretical proposals over 25 years, the pairing glue as well as the nature of the normal states are still not clearly identified. The enigmatic pseudogap phase, characterized by the loss of spectral weight above the superconducting transition temperature (Tc ), is believed to be a key to understanding the superconductivity. This dissertation primarily investigates the underdoped BSCCO, a double layered cuprate perovskite which exhibits pseudogap over wide range. Spectroscopic-Imaging Scanning Tunneling Microscopy (SI-STM) is a unique probe in that it allows simultaneous access to complimentary spaces. For SI-STM can visualize the electronic structure of a physical system with atomic resolution and register in real space, with its Fourier-transform revealing the dispersion of quasiparticle excitations in momentum space. Three discoveries made with SI-STM are presented here. First, the real-space electronic nematicity observed within CuO2 unit cell demonstrates that the C4 rotational symmetry of the underlying crystal lattice is broken into the C2 symmetry in the electronic structure. Inequivalence of the orthogonal crystallographic axes narrows down the possible models for pseudogap in favor of stripe order. Momentum space provides two other discoveries. Ratio of the differential conductance data measured at opposite bias voltage, which amplifies the particle-hole symmetric dispersion of the Bogoliubov quasiparticle, shows that the pseudogap state retains the tri-partite electronic excitation structure present below Tc . The signature of the Cooper pairs without long-range phase coherence renders the pseudogap as a pre-cursor to the superconducting state. In contrast, the anti-nodal charge-ordering dominant in the raw data but washed out in the ratio map is found to weakly disperse in a continuous but asymmetric manner. The peculiarity of the dispersion distinct in the strongly underdoped regime of cuprate family with high maximum Tc is discussed in the context of the low-energy psdueogap in the last chapter.

▼ Superconductivity is a result of quantum coherence at macroscopic scales. Two superconductors separated by a metallic or insulating weak link exhibit the AC Josephson effect: the conversion of a DC voltage bias into an AC supercurrent. This current may be used to activate mechanical oscillations in a suspended weak link, acting as an electromechanical resonator. As the DC voltage bias condition is remarkably difficult to achieve in experiments, here the experimentally relevant purely DC current bias case is analyzed thoroughly. It shall be demonstrated that the Josephson effect can be exploited to activate and detect mechanical oscillations, eliminating the need for AC bias conditions that are generally required for nanoelectromechanical systems (NEMS). The coupling between the electronic and mechanical degrees of freedom may be tuned by an external magnetic field, allowing the exploration of the Josephson effect in two distinct coupling regimes. In the weak coupling regime, Shapiro-like plateaus and mechanically induced hysteresis loops develop in the junction's current-voltage (I-V) characteristic which allow for precision measurements of the resonator's resonance frequency by simple DC voltage measurements. In contrast, in the strong coupling regime there are sudden mechanically induced transitions to a zero voltage state which will be explained by energy sharing between the electronic and mechanical degrees of freedom. These transitions are intimately linked to the mechanical damping of the resonator, and may be used to determine the junction's quality factor, again with only DC voltage measurements. It is further revealed that these sudden transitions may be eliminated by using a setup consisting of two suspended weak links connected in parallel forming a superconducting quantum interference device (SQUID), and tuning the external magnetic flux appropriately. Finally, the quantum nature of Josephson junctions is explored more thoroughly by considering Bloch-like oscillations that develop in the junction. These oscillations, when coupled to mechanical vibrations, generate non-classical mechanical states that are intimately linked to the quantum dynamics of the junction.

▼ Under high pressure, simple molecular solids transform into non-molecular (extended) solids as compression energies approach those of strong covalent bonds in constituent chemical species, often with advanced mechanical, optical, electronic, and magnetic properties. The primary goal of this research is to investigate the pressure-induced molecular to nonmolecular solids, via discoveries of new states, structures, fundamental properties, and novel phenomena in carbon disulfide and its chemical analogs under extreme conditions of pressure and temperature.Spectral, structural, resistance, and theoretical evidences show simple molecular CS2 undergoes transformations to an insulating black polymer with three-fold carbon atoms at ~9 GPa, to a semiconducting polymer above 30 GPa, and finally to a metallic solid above 50 GPa. The metallic phase is a highly disordered 3D network structure with four-fold carbon atoms. Based on first-principles calculations, we consider two plausible structures for the metallic phase: α-chalcopyrite and tridymite, both exhibiting metallic ground states.Remarkably, low-temperature, dense CS2 not only becomes metallic, but also shows the coexistence of superconductivity and spin-fluctuations. This is the first such observation of superconductivity in simple diamagnetic molecular solids like CS2 at high pressure. The superconductivity in CS2 arises from a highly disordered state at a relatively high transition temperature of ~6.2 K and is, interestingly, preceded by a magnetic ordering transition at ~45.2 K. Based on the x-ray scattering data, we suggest that the local structure changes from tetrahedral to octahedral and the associated spin-fluctuations are responsible for the observed magnetic ordering and superconductivity. A number of related molecular analogs and main group IV disulfides were also studied at high pressure and revealed systematic trends.The above-mentioned findings are important for understanding novel properties of 3D extended solids, the nature of interactions and chemical bonds, and fundamental rules of high-pressure physics and chemistry. The discovery of superconductivity in CS2 is significant for applications and justifies a search for other potential high Tc superconductors composed of low-Z 3D network structures with high phonon frequencies. This is unlike other, more typical, organic superconductors of charge-transferred salts or metal-doped carbons and, most certainly, will stimulate future experimental and theoretical studies.

▼ The superconductivity in CaFe2As2, both at ambient and elevated pressures, remains an open question. Both interface-associated superconductivity and spontaneous phase separation (producing a new phase at low temperature) have been proposed. Thus far, superconductivity has been only observed below 12 K and within a narrow pressure range. As the evidence for filamentary superconductivity, a slight resistivity drop below 10 K has only been detected in a few extraordinary CaFe2As2 samples. In this dissertation we show that superconductivity with a noticeable Meissner effect and a Tc up to 25 K can be induced at ambient pressure. These occur only when the two coexisting phases, i.e., the tetragonal-to-orthorhombic phase P1 and the tetragonal-to-collapsed tetragonal phase P2, are mesoscopically organized in a layer-stacking manner. The X-ray diffraction profile-analysis reveals a possible formation of dense interfaces, which is correlated with the superconductivity. The magnetic data further suggest that the spin-density-wave excitation in the P1 phase is largely suppressed along the interfaces. The microstress along the interfaces, therefore, may play a crucial role in the interface-associated superconductivity. The ambient-pressure superconducting CaFe2As2 sample we obtained unexpectedly demonstrates two superconducting transitions under high pressure from 0 to 17 kbar, and they have distinctive responses to external pressure. The higher transition with Tc ~25 K at ambient pressure can be further enhanced to 30 K under a pressure of 17 kbar. The pressure study further supports that the enhanced Tc is associated with the interfaces between phase P1 and P2. The work presented in this dissertation provides the most direct evidence for interface-enhanced Tc in undoped CaFe2As2 to date. To further explore other possible Tc enhancement in CaFe2As2, doping studies with Sm and Eu were also conducted. Superconductivity has been observed in the samples with Sm doping at ambient pressure and in the samples with Eu doping under high pressures. Related work are also presented as we attempted to search for enhancement of superconductivity in another layered compound beta-PdBi2. Advisors/Committee Members: Chu, Paul C. W.

▼ The developments over the last decade in Focused Ion Beam (FIB) instrument technology have reached a point where there is sufficient control of an ion beam to make cuts, trenches, and other shapes in a sample on a scale of tens of nanometers. This work concentrates on the use of an FIB instrument for making superconducting devices. It is shown for the first time that planar-bridge (Nb/Cu/Nb) Superconductor/Normalmetal/ Superconductor (SNS) junctions can be reliably fabricated using a standard FIB instrument. This is demonstrated by the responses of junctions to microwaves and magnetic fields; the junctions display the appropriate Josephson behaviour demanded by current technological applications. In addition, the reproducibility in junction behaviour (the variation of critical current is approximately 10%) is the best so far observed for this type of junction. The SNS junction fabrication method has been successfully extended for making high-density SNS junction arrays, dc-SQUIDs, and related devices. A simple model is devised to explain the normal-state resistance and critical current of a junction. The model is based on the geometry of a junction as defined by the FIB instrument and the film deposition. The model is mostly successful in qualitatively explaining many of the geometrical factors that affect the electrical properties of the junction. Nb/Cu/Nb junction series arrays, made using an FIB instrument, are also successfully fabricated. The yield of the junctions forming small arrays is found to be similar to the yield of single junctions. For the series arrays studied here, new observations have been made: the electrical properties of an array have been found to be dependent on the spacing of the junctions and the number of junctions in the array. This work also investigates the thermal properties of SNS and micron-scale superconductor/insulator/normal-metal junction based devices for use in bolometer device based applications. It is shown that self-heating raises the temperature of the junctions significantly above their operating temperatures. For a device sitting on a low thermally conductive membrane, it is found that the effects of heating, or cooling, in the junctions are exaggerated.

▼ Large electrical current transport in the absence of energy losses is the key factor in commercial applications of high temperature superconductors. This thesis demonstrates an easy and inexpensive bottom-up technique to produce self assembled nanorods, segmented nanorods as well as nanoparticles in YBa2Cu3O7-δ thin films grown by pulsed laser deposition. The structural and morphological characteristic of the pinning landscapes produced are investigated and correlated to their effects on the superconducting properties of the thin films. In particular two pinning landscapes are investigated: Ba2YNbO6 nanorods are grown in YBa2Cu3O7-δ thin films using a Ba2YNbO6 doped YBa2Cu3O7-δ pulsed laser deposition targets and Ba2(Y/Gd)(Nb/Ta)O6 segmented nanorods together with (Y/Gd)2O3 nanoparticles are grown in (Y/Gd)Ba2Cu3O7-δ thin films using a Ba2YNbO6 + Gd3TaO7 doped YBa2Cu3O7-δ pulsed laser deposition targets. The Ba2YNbO6 + YBa2Cu3O7-δ is deeply characterised and the effects of the deposition parameters are analysed. Ba2YNbO6 is demonstrated to be an interesting novel pinning addition capable to increase the critical current and to reduce the YBa2Cu3O7-δ critical currents angular dependencies anisotropy. The Ba2YNbO6 + Gd3TaO7 + YBa2Cu3O7-δ is found to produce a new complex pinning landscape extremely effective. At high fields the synergetic combination of the different defects typology is shown to generate an interesting new feature in the critical current angular dependencies. Chapter 1 is an introduction to superconductivity, the fundamentals of the field are briefly presented. In chapter 2 the discussion in focused on pinning in high temperature superconductors. Cuprates and in particular YBa2Cu3O7-δ are presented. The pinning phenomenon and the practical pinning engineering in thin films is also discussed in this chapter. Chapter 3 describes the thin films preparation methods and the characterisation techniques used in the research work. Chapter 4 and 5 are focused on the Ba2YNbO6 doped YBa2Cu3O7-δ thin films. Chapter 4 is an introduction to Ba2YNbO6 doped YBa2Cu3O7-δ, the preliminary results obtained on Ba2YNbO6 doped YBa2Cu3O7-δ thin films are shown in this chapter. The crystalline structure, the morphology and the superconducting properties of thin films deposited adopting different deposition parameters are analysed and discussed in chapter 5. In chapter 6 the new complex pinning landscape of Ba2(Y/Gd)(Nb/Ta)O6 and (Y/Gd)2O3 in (Y/Gd)Ba2Cu3O7-δ is presented. Concluding remarks on the research described in the work ends the thesis in a brief final chapter 7.
