Title: Superconductivity in $Y_{7} R u_{4} InG e_{12}$

Abstract

We report a type-II intermetallic superconductor Y₇Ru₄InGe₁₂ with a transition temperature (T_c) of ~5.8 K, which is confirmed by zero resistivity, diamagnetic magnetic susceptibility, and specific-heat jump. Single crystals of Y₇Ru₄InGe₁₂ were grown from a reactive indium flux. Y₇Ru₄InGe₁₂ crystallizes in the tetragonal space group P4/m and features a [Ru₄InGe₁₂] polyanionic network with Y atoms located in three different channels. The upper critical fields of Y₇Ru₄InGe₁₂ at 0 K are determined to be ~5.3 and 2.4 T along the c axis and the ab plane, respectively. The estimated coherence length along the c axis (~174 Å) is much larger than the estimated mean free path along the c axis (~29 Å) in Y₇Ru₄InGe₁₂, placing its superconductivity in the so-called dirty regime. The compound exhibits a large superconducting specific-heat jump ΔC/γeT_c ≈ 2.4, significantly well above the weak-coupling Barden-Cooper-Schrieffer theoretical value of 1.43 and pointing to a strong-coupling scenario in Y₇Ru₄InGe₁₂. As a result, density-functional-theory calculations show that the density of states in Y₇Ru₄InGe₁₂ exhibits a broad peak near the Fermi level which mainly derives from Y–4d,Ru–4d, and Ge–4p states.

Anisotropic $H_{c 2}$ , thermodynamic and transport measurements, and pressure dependence of $T_{c}$ in $K_{2} {Cr}_{3} {As}_{3}$ single crystals

Journal Article Kong, Tai ; Bud'ko, Sergey L. ; Canfield, Paul C. - Physical Review. B, Condensed Matter and Materials Physics

We present a detailed study of single crystalline K₂Cr₃As₃ and analyze its thermodynamic and transport properties, anisotropic H_c2(T), and initial pressure dependence of T_c. In zero field, the temperature-dependent resistivity is metallic. Deviation from a linear temperature dependence is evident below 100 K and a T³ dependence is roughly followed from just above T_c (~10K) to ~40K. Anisotropic H_c2(T) data were measured up to 140 kOe with field applied along and perpendicular to the rodlike crystals. For the applied field perpendicular to the rod, H_c2(T) is linear with a slope ~–70 kOe/K. For field applied along the rod, the slopemore »« less

We report the magnetic and electronic properties of the bilayer ruthenate Sr₃Ru₂O₇ upon Fe substitution for Ru. We find that Sr₃(Ru_1-xFe_x)₂O₇ shows spin-glass-like phase below 4 K for x = 0.01 and commensurate E-type antiferromagnetically ordered insulating ground state characterized by the propagation vector q_c = (0.25 0.25 0) for x ≥ 0.03, in contrast to the paramagnetic metallic state in the parent compound with strong spin fluctuations occurring at wave vectors q = (0.09 0 0) and (0.25 0 0).

Evolution of magnetism in single-crystal $C a_{2} R u_{1 - x} I r_{x} O_{4} (0 \leq x \leq 0.65)$

Journal Article Yuan, S. J. ; Terzic, J. ; Wang, J. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, we report structural, magnetic, transport, and thermal properties of single-crystal Ca₂Ru_1-xIr_xO₄(0≤x≤0.65). Ca₂RuO₄ is a structurally driven Mott insulator with a metal-insulator transition at T_MI=357K, which is well separated from antiferromagnetic order at T_N=110K. Substitution of a 5d element, Ir, for Ru enhances spin-orbit coupling and locking between the structural distortions and magnetic moment canting. Ir doping intensifies the distortion or rotation of Ru/IrO₆ octahedra and induces weak ferromagnetic behavior along the c axis. In particular, Ir doping suppresses T_N but concurrently causes an additional magnetic ordering T_N2 at a higher temperature up to 210 K for x=0.65.more »« less

Effect of Ni doping on vortex pinning in $CaK {(F e_{1 - x} N i_{x})}_{4} A s_{4}$ single crystals

We study the correlation between chemical composition and vortex dynamics in Ni-doped CaK(Fe_1–xNi_x)₄As₄ (x = 0, 0.015, 0.025, 0.03, and 0.05) single crystals by performing measurements of the critical current densities J_c and the flux creep rates S. The magnetic relaxation of all the crystals is well described by the collective creep theory. The samples display a glassy exponent μ within the predictions for vortex bundles in a weak pinning scenario and relatively small characteristic pinning energy (U₀ < 100K). The undoped crystals display modest J_c values at low temperatures and high magnetic fields applied along the c axis. J_c(T)more »« less

Quasi-two-dimensional fluctuations in the magnetization of $L a_{1.9} C a_{1.1} C u_{2} O_{6 + δ}$ superconductors

Journal Article Shi, Xiaoya ; Dimitrov, I. K. ; Ozaki, Toshinori ; ... - Physical Review B

We report the results of magnetization measurements with the magnetic field applied along the c axis on superconducting La_1.9Ca_1.1Cu₂O_6+δ single crystals processed under ultrahigh oxygen pressure. Strong fluctuation effects were found in both low- and high-field regimes. Scaling analysis of the high-field magnetization data near the critical temperature (T_c = 53.5K) region reveals the characteristics of critical fluctuation behavior of quasi-two-dimensional (2D) superconductivity, described by Ginzburg-Landau theory using the lowest Landau level approximation. Low-field magnetic susceptibility data can be successfully explained by the Lawrence-Doniach model for a quasi-2D superconductor, from which we obtained the a b plane Ginzburg-Landau coherence lengthmore »« less
