最近报道了某些金属的三元钼硫化物的有趣的超导性能。含锡和含铅化合物的超导转变温度(T_0)分别为14和15°K,还报道说这些化合物的上临界场(Hc_2)在50万高斯以上。这些三元钼硫化物的Hc_2值比任何其他已知超导体的Hc_2值都高。因此,在有关超导材料的计划中,作者研究了某些金属的三 The interesting superconductivity of some metal ternary molybdenum sulfides has recently been reported. The superconducting transition temperatures (T_0) of tin and lead-containing compounds are 14 and 15 ° K, respectively. It is also reported that the upper critical field (Hc_2) of these compounds is above 500000 Gauss. The Hc_2 values ​​of these ternary molybdenum sulfides are higher than those of any of the other known superconductors. Therefore, in the planning of superconducting materials, the author studied some of the metals III
