  (Pt0.2Ir0.8)3Zr5 的低温手性晶体结构和超导性

  摘要：

  我们报告了在手性空间群( P 6 1 22)的(Pt 0.2 Ir 0.8 ) 3 Zr 5中在低温下观察到的超导性。使用比热测量证实了 2.2 K 转变温度下超导性的体积性质。我们发现(Pt 0.2 Ir 0.8 ) 3 Zr 5服从弱耦合Bardeen-Cooper-Schrieffer模型，上临界场的主导机制是轨道破对极限而不是Pauli-Clogston极限。这表明手性晶体结构引起的反对称自旋轨道耦合并没有显着影响(Pt 0.2 Ir 0.8 ) 3 Zr 5的超导性。

  We report the observation of superconductivity in (Pt0.2Ir0.8)3Zr5 with a chiral space group (P6122) at low temperatures. The bulk nature of the superconductivity at a transition temperature of 2.2 K was confirmed using specific heat measurements. We revealed that (Pt0.2Ir0.8)3Zr5 obeys the weak-coupling Bardeen–Cooper–Schrieffer model, and the dominant mechanism in the upper critical field is the

  Syntheses, structural and compositional analyses of the filled cubic Ti2Ni-type phase in Zr-Pt-O system have been studied, largely for the platinum-richer compositions. Diffraction quality Crystals were grown by annealing an arc-melted composition Zr4Pt2O0.66 at 1600 degrees C under Ar. The refined composition Zr4.0Pt1.95(1)O0.93(6) (a = 12.5063(6) angstrom, Fd (3) over barm, Z = 16) is close to the idealized composition Zr4Pt2O known in several other Zr-T-O systems (T = late 4d or 5d transition element). (This composition has been erroneously reported by ICDD for years as Zr6Pt3O (No. 00-017-0557) and referred to as epsilon-Zr6Pt3O.) The product is only marginally poor in platinum and oxygen, in contrast to the 1960 reports of metallographic studies (similar to Zr4Pt1.62O0.44). Under arc-melting conditions, high yields of the cubic phase are obtained from samples with lower platinum concentrations (Zr4Pt1.74O1.04), whereas samples near the refined cubic composition contain hexagonal Zr(5)pt(3)O(x) as well (Mn5Si3-type). The hexagonal structure of binary Zr5Pt3 was also refined (Mn5Si3 type, P6(3)/mcm, a = 8.210(1) angstrom, c = 5.385(2) angstrom) and shown to be non-stoichiometric to at least Zr5Pt2.5.
