摘要

鉴定出（TiZrHf）95Sc5的三个多态，其中一个为玻璃态。该材料是由飞溅冷却电弧熔化样品制成的。体心立方和非晶材料的电阻率随温度的变化是反常的。低温电阻率和热容量测量表明，当材料具有体心立方（TC ~ 1.5 K）或六方密排（TC ~ 0.8 K）晶体结构时，存在超导转变，并且不能排除低于0.65 K的非晶相的超导性。我们在体心立方材料中加入了一个强大的临界场的证据。

Anomalous resistivity and superconductivity in the polymorphs of (TiZrHf)95Sc5

Three polymorphs of (TiZrHf)₉₅Sc₅, one of which is glassy, are identified. The materials are the result of splat cooling arc melted samples. The temperature-dependent resistivities of the body centered cubic and amorphous materials are anomalous. Low temperature resistivity and heat capacity measurements indicate that superconducting transitions are present when the material has either a body centered cubic (T_C ∼ 1.5 K) or hexagonal close packed (T_C ∼ 0.8 K) crystal structure and the superconductivity of the amorphous phase below 0.65 K cannot be ruled out. We include evidence of a robust critical field in the body centered cubic material.
