▼ 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..

▼ There exist several classes of materials that simultaneously exhibit superconductivity and anomalous magnetic order, where both effects are homogeneous throughout the material. No cohesive explanation for this “apparent ferromagnetism” has ever been published. In the A(1-x)CexSr2Cu2MO10 and in the ASr2Cu2RuO8 (A=Ln,Y; M=Ru,Nb) families of materials, it is shown via diffraction, SQUID magnetometry, and electron spin resonance that the metamagnetism in these materials is due to CuO 2 ferromagnetic order in the ab-plane, with adjacent layers stacked ferromagnetically; this CuO2 magnetic order coexists with superconductivity in these materials. The implications of this on models of high-TC superconductivity may be profound. Another controversial class of superconducting material, Ba2ARu(1-x)CuxO6 (A=Ln,Y) is examined and the compound Ba2YRu(1-x)CuxO6 is shown to be superconducting with simultaneous Cu magnetic order at temperatures near that of YBCO, without CuO2 planes. The magnetic and crystal structures of several members of the Ln series are examined by SQUID magnetometry, electron spin resonance, and x-ray and neutron diffraction, with discovery of simultaneous superconductivity and Cu magnetic order in only Ba2DyRu(1-x)CuxO6. A third related class of materials, La2CuMO6 (M=Ru,Nb,Ti,Ir,Sn) is also examined for superconductivity. The magnetic structure of these materials is investigated by diffraction and SQUID magnetometry, and new high-temperature synthesis techniques are performed that dramatically improve the structural and magnetic properties of the compound La2CuRuO6; electron spin resonance has identified Cu antiferromagnetism in this material for the first time. Hole doping (with Ba or Sr) and electron doping (with Ce or Th) fails to generate superconductivity in this material. The high-temperature synthesis techniques are unsuccessful in processing of other members of the La 2CuMO6 family due to the stability of La 2M2O7-type compounds at high temperatures. The compound La2CuSnO6 forms distinct CuO2 and SnO2 chemical layers, yet shows no superconductivity.

Strong correlations between electrons often generate unexpected new collective behavior that we call emergent phenomena. Strong interactions can ramp up the relevant scales, creating massive electrons in heavy fermion materials and high transition temperatures in superconductors, or lead to entirely new states of matter with low energy excitations containing a fraction of the original electron. These phenomena provide unique challenges to theorists as they sit at the intersection of kinetic and potential energy scales, where perturbative many body techniques fail. One useful method here is the large N approach, which generalizes the number of components of the electron spin from 2 to N, providing an artificial perturbation expansion about a strongly correlated state which, if chosen properly, captures the essential physics. To do so, we must ensure that the large N limit maintains the important symmetries. While SU(N) is the traditional large-N limit, not all SU(N) spins invert under time-reversal for N > 2. To treat phenomena like frustrated magnetism and superconductivity that contain particle-particle singlets, we must restrict ourselves to the subgroup of time-reversing spins, SP(N), a large N limit we call symplectic-N. The correspondance of time-reversal and symplectic symmetry, and its consequences for spin and Hubbard operator representations are discussed in Chapter 2, which provides the mathematical backbone of this dissertation. Chapter 3 develops a symplectic-N treatment of frustrated magnetism, treating ferromagnetic and antiferromagnetic correlations on equal footing, before we move on to unconventional superconductivity. First we show how composite pairs, bound states between local moments and conduction electrons in two orthogonal symmetry channels, emerge from the large N limit of the two channel Kondo model in Chapter 4, and then discuss how composite pairing interacts cooperatively with magnetic pairing in Chapter 5. In Chapter 6, we examine the interplay of composite pairing and valence fluctuations in the two-channel Anderson model. Finally, Chapter 7 studies the effect of Coulomb repulsion on s +/- pairing in a t-J model of the iron-based superconductors.

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 describes the development of single crystal x-ray scattering applied to the study of charge stripes in some exotic transition-metal oxides. Charge stripes in the cuprates and manganites are strongly associated with high T(_c) superconductivity and colossal magnetoresistance, and can be characterised by the satellite reflections located around related Bragg peaks below the charge ordering transition temperature ( T(_co). The intensities of these extremely weak satellite reflections are between l0(^-4) and 10(^-6) less than those of Bragg reflections, thus very high brilliant rotating-anode x-ray and synchrotron radiation sources are required to study them. The structure factors and correlation lengths of the charge stripes can be directly obtained by measurements of the integrated intensities and peak widths of the charge ordering satellite reflections as a function of temperature. The charge stripes in single crystals of Bi(_0.24)Ca(_o.76)MnO(_3), Nd(_0.5)Sr(_0.5)MnO(_3) and La(_5/3)Sr(_1/3)NiO(_4) have been comprehensively characterised using both laboratory and synchrotron radiation x-ray scattering. The measurements on Bi(_0.24)Ca(_0.76)MnO(_3) directly demonstrate a strong relationship between the charge stripe ordering and the first-order structural phase transition, which is common in many perovskite manganites. Direct evidence for the existence of perpendicular charge-ordered domains in manganites was obtained for the first time by x-ray scattering in Nd(_0.5)Sr(_0.5)MnO(_3), and this result demonstrates that charge stripes have complex structures in the mesoscopic length scale. Scattering was also observed at the positions in reciprocal space associated with spin ordering into stripes. These showed evidence of different critical behaviour than the corresponding charge stripe satellites. The quasi two-dimensional feature of the charge stripes in La(_5/3)Sr(_1/3)NiO(_4) was successfully demonstrated by the critical exponents of the charge stripe melting and by the measurements of their m-plane and out-of-plane correlation lengths. Experimental evidence for the existence of electronic liquid crystal phases in La(_5/3)Sr(_1/3)NiO(_4) was obtained, in agreement with recent theoretical predictions

▼ Superconductivity is a field where much research has been conducted into explaining all aspects of this phenomenon in many materials. BCS theory provided the principal understanding of superconductivity in conventional materials yet fails to entirely describe those which exhibit greater coupling-strengths as well as the more unconventional superconductors. Formulations have been proposed which extend BCS theory in various ways such as scaling the predicted energy gap by values representative of greater coupling strengths. In order to further extend such formulations we applied our own theory which recalculates the energy gap based solely on thermodynamic parameters, in the hope of improving their accuracy. Comparisons of this energy gap calculated from existing critical-field measurements as well as computational predictions for a range of weak- to strong-coupling type I s-wave superconductors were made with experimental tunnelling measurements. Our thermodynamic theory provided an accurate temperature-dependence of the energy gap for all these superconductors except for the strongest coupler which produced erroneous predictions. An extra-strong-coupling superconductor Pb₀.₇Bi₀.₃ was synthesised and it’s critical-field measured in order to rigorously test our theory in the strong-coupling regime. It exhibited type II superconductivity contrary to our belief and as such measurements were insufficient for an accurate comparison. However, computational calculations predicted an accurate temperature-dependence for the energy gap of Pb₀.₇Bi₀.₃ when compared with experimental tunnelling measurements. Thus our theory appears to apply for this extra-strong-coupling type II superconductor and not for the strong-coupling type I superconductor, which prompts further investigation. These comparisons depend upon the accuracy with which the temperature-dependence of the energy gap can be measured - not an easy task. Extension was also made to d-wave superconductivity where our theory provided little improvement over a scaled BCS interpretation for several overdoped samples of the unconventional Bi-2212 superconductor. However, and this is a most important conclusion, this is due to the weak nature of the coupling in this material which we were able to establish. Thus our theory appears to provide several promising first-order results and warrants further investigation and application to a range of superconductors.

▼ The superconducting properties of low dimensional superconductors, in which one or more dimensions are comparable with the coherence length, differ significantly from bulk superconductors. Basic properties such as the critical temperature and the critical fields can be tuned by varying the size of the specimen. Unfortunately, thermal fluctuations are strongly enhanced in low dimensionality. They cause dissipation and destroy the long-range-ordered state at finite temperature. In 1D superconducting wires, thermal fluctuations induce slips in the phase of the order parameter, resulting in non-zero resistance at any finite temperatures below the critical temperature T_c. These thermally-activated phase slip (TAPS) processes are theoretically described by the Langer–Ambegaokar–McCumber–Halperin (LAMH) theory. Unlike in 1D superconductors, a quasi-long-range-ordered phase-coherent state is possible through the famous Berezinskii-Kosterlitz-Thouless (BKT) transition, which occurs below the mean field critical temperature T_c in continuous 2D superconducting films or 2D Josephson junction arrays. Vortices with opposite vorticity form bound pairs below the BKT transition temperature T_BKT. This establishes a dissipationless quasi-long-range-ordered superconducting state. This spectacular feature in 2D Josephson junction arrays has been demonstrated to provide a possibility for phase-coherent superconductivity in arrays of weakly-coupled 1D superconductors. The resulting phase-ordering transition between neighboring superconducting chains in the lateral plane then instantly quenches the phase slips in individual wires and long-range phase coherence in both the transverse and longitudinal directions is achieved. A 3D bulk superconducting state is therefore possible in such a quasi-1D superconductor where individual 1D superconducting atomic chains or nanowires is weakly coupled to their neighbors. In this thesis, the superconducting properties of quasi-1D superconductors, including 5 nm Pb nanowire arrays embedded in the pores of mesoporous silica SBA-15 and the quasi-1D carbide superconductor Sc₃CoC₄, as well as the properties of 2D superconductivity at the interface of Bi₂Te₃/FeTe have been studied in great detail.The 5 nm Pb nanowire arrays were fabricated in the 6 nm pores of mesoporous silica SBA-15 by Prof. Xijun Hu and Prof. Frank L. Y. Lam using a chemical vapor deposition (CVD) method. Weakly-coupled superconductor-insulator-superconductor (SIS) junction arrays are formed in this system. The superconducting properties of these 5 nm Pb nanowire arrays were studied in detail by means of bulk DC magnetization, specific heat and electrical transport measurements. The experimental results indicate that the superconducting fluctuations survive up to 10~11 K, which is 3~4 K above the bulk critical temperature of 7.2 K of Pb. Zero resistance is reached below 2 K. More interestingly, the upper critical field is observed to be ~15 T and is enhanced by…

▼ Superconductivity presents itself many peculiar and interesting properties in different dimensionalities, which have attracted much attention ever since it has been discovered in bulk materials. At an early stage, theoretical models were established in 3D regimes to describe the conventional bulk superconductivity, while superconductivity was also gradually observed and well studied in 2D, 1D and 0D materials, both experimentally and theoretically. Nevertheless, new superconducting materials are emerging regularly, with novel phenomena, unknown mechanisms and the potential to future applications. This makes superconductivity so charming that people never let up the efforts to further excavate and explore the mystery of superconductors. In this thesis work, I will investigate superconductivity in several materials, including a Nb doped bulk topological insulator (Nb_xBi₂Se₃), 2D interfacial superconductor (Bi₂Te₃/Fe_1+yTe) and 1D nanowires (Sn and Al). The basic concepts of superconductivity and corresponding microscopic theories will be introduced in Chapter 1, including the London equation, the Ginzburg-Landau theory and the Bardeen-Cooper-Schrieffer (BCS) theory. Especially, the BCS theory is applicable to conventional superconductors, of which electrons can be weakly bonded as Cooper pairs and move without any resistance below the superconducting transition temperature T_c. However, in low dimensionality, thermal fluctuation activated phase slips of the order parameter will be enhanced and result in a finite resistance in 1D or 2D materials below T_c. For 1D superconductors, such a process has been well explained by the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory. For 2D superconducting materials (thin films or Josephson junctions), vortex-antivortex bonded pairs can form a quasi-long-range-ordered phase coherent state in the 2D plane below a characteristic temperature T_BKT, which is slightly lower than T_c. Therefore, a zero resistance state could also be established in 2D films or Josephson junctions, which fall in the same universality class, and such a transition is described by the well-known Berezinskii-Kosterlitz-Thouless (BKT) theory. Various instruments and methods have been involved in this thesis work, which will be briefly described in Chapter 2. Mainly, I focus on the transportation properties and magnetization investigations, and one of my frequently used techniques, the point-contact spectroscopy, will be thoroughly discussed with the corresponding theoretical model, the Blonder-Tinkham-Klapwijk (BTK) model, being presented. In the following Chapter 3, a study of the upper critical field transition in Nb doped Bi₂Se₃ by field-angle-resolved resistive and magnetization measurements will be presented. 3D topological insulators (TI) could become superconducting by doping with intercalation of metallic ions, such as Cu_xBi₂Se₃,…

▼ The focus of this thesis is the study of superconducting resistive transition in 4-Å carbon nanotube arrays embedded in the aligned, linear pores of AFI zeolite crystals. While superconductivity was discovered in this material system one decade ago, resistive transition was not observed at that time owing to inadequate sample quality. The present study remedies this situation with samples fabricated from a new approach. Two types of superconducting resistive behaviors were observed in different selective samples. The first is the quasi one dimensional (1D) fluctuation superconductivity, which exhibits a smooth resistance drop with decreasing temperature, initiating at 15 K. At low temperatures, the differential resistance also shows a smooth increase with increasing bias current. Both are not affected by a magnetic field up to 11 Tesla. Such manifestations are consistent with the 1D superconducting characteristics as qualitatively interpreted by the mechanism of thermally activated phase slips, within the framework of the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory. A competing mechanism with the 1D superconductivity, the Peierls distortion, is shown to manifest itself as a differential resistance peak (as a function of the driving current), appearing above a certain temperature. Theoretical calculations suggest the quasi-1D superconducting behavior to arise from thin arrays of (5,0) 4-Å carbon nanotubes, each comprising a central member surrounded by at least six others, with a wall-to-wall separation of ~1 nm as dictated by the molecular structure of the AFI zeolite crystal. These thin (5,0) nanotube arrays plausibly act as the critical electrical links bridging the measuring electrodes. The second type of observed superconducting behavior is the one dimensional (1D) to three dimensional (3D) superconducting crossover transition. In four samples, the transition was observed to initiate at 15 K with a slow resistance decrease switching to a sharp, order of magnitude drop at ~7.5 K. The latter exhibits anisotropic magnetic field dependence, and the differential resistance versus bias current show a rich variety of details that are consistent with the establishment of coherence, in stages, as the temperature is lower below 15 K. In particular, the resistance drop that starts at 7.5 K exhibits attributes that are consistent with the manifestations of a Berezinskii-Kosterlitz-Thouless transition that establishes quasi-long-range order in the plane transverse to the c-axis of the aligned nanotubes, thereby mediating a 1D to 3D crossover. The electrical transport data and their interpretation are supported by the magnetic and specific heat results obtained by the group of Prof. Rolf Lortz.
