Title: Anisotropy reversal of the upper critical field at low temperatures and spin-locked superconductivity in $K_{2} {Cr}_{3} {As}_{3}$

Abstract

We report measurements of the anisotropic upper critical field H_c2(T) for K₂Cr₃As₃ single crystals up to 60 T and T>0.6K. Our results show that the upper critical field parallel to the Cr chains, H^∥_c2(T), exhibits a paramagnetically limited behavior, whereas the shape of the H^⊥_c2(T) curve (perpendicular to the Cr chains) has no evidence of paramagnetic effects. As a result, the curves H^⊥_c2(T) and H^∥_c2(T) cross at T≈4K, so that the anisotropy parameter γ_H(T)=H^⊥_c2/H^∥_c2(T) increases from γ_H(T_c)≈0.35 near T_c to γ_H(0)≈1.7 at 0.6 K. The paramagnetically limited behavior of H^∥_c2(T) is inconsistent with triplet superconductivity but suggests a form of singlet superconductivity with the electron spins locked onto the direction of Cr chains.

Anisotropic thermodynamic and transport properties of single-crystalline ${CaKFe}_{4} {As}_{4}$

Journal Article Meier, W. R. ; Kong, T. ; Kaluarachchi, U. S. ; ... - Physical Review B

We grew single-crystalline, single-phase CaKFe₄As₄ out of a high-temperature, quaternary melt. Temperature-dependent measurements of x-ray diffraction, anisotropic electrical resistivity, elastoresistivity, thermoelectric power, Hall effect, magnetization, and specific heat, combined with field-dependent measurements of electrical resistivity and field and pressure-dependent measurements of magnetization indicate that CaKFe₄As₄ is an ordered, stoichiometric, Fe-based superconductor with a superconducting critical temperature, T_c=35.0±0.2 K. Other than superconductivity, there is no indication of any other phase transition for 1.8K≤T≤300 K. All of these thermodynamic and transport data reveal striking similarities to those found for optimally or slightly overdoped (Ba_1-xKx)Fe₂As₂, suggesting that stoichiometric CaKFe₄As₄ is intrinsically close to what is referred to as “optimal-doped” on a generalized, Fe-based superconductor, phase diagram. Furthermore, the anisotropic superconducting upper critical field, H_c2(T), of CaKFe₄As₄ was determined up to 630 kOe. The anisotropy parameter γ(T)=Hmore »« less

Critical behavior of the quasi-two-dimensional weak itinerant ferromagnet trigonal chromium telluride ${Cr}_{0.62} Te$

Journal Article Liu, Yu ; Petrovic, C. - Physical Review B

The critical properties of flux-grown single-crystalline quasi-two-dimensional weak itinerant ferromagnet Cr_0.62 Te were investigated by bulk dc magnetization around the paramagnetic to ferromagnetic phase transition. Critical exponents β = 0.315 ( 7 ) with a critical temperature T_c = 230.6 ( 3 ) K and γ = 1.81 ( 2 ) with T_c = 229.1 ( 1 ) K are obtained by the Kouvel-Fisher method whereas δ = 6.35 ( 4 ) is obtained by a critical isotherm analysis at T c = 230 K. With these obtained exponents, the magnetization-field-temperature curves collapse into two independent curves following amore »« less

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
