摘要:

本文研究了122型固溶体Sr_(1-x)Ni_2 P_2的结构演化和超导电性。我们发现在x = 0.5时发生正交-四方结构的相变,其特征是P-P二聚体的断裂。超导转变温度在x = 0.4时表现出最高值2.85 K。

英文摘要:

The structural evolution and superconductivity of a 122-type solid solution Sr1-xBaxNi2P2 were studied. We found that an orthorhombic-tetragonal structural phase transition takes place at x = 0.5, and is characterized by the P-P dimers breaking. The superconducting transition temperature exhibited its highest value of 2.85 K at x = 0.4.
