高T_c 氧化物超导体的一个经验规律

AN EMPIRICAL RULE OF HIGH Tc OXIDE SUPERCONDUCTORS

本文对近两年来发现的高 Tc 氧化物超导体进行了分析,发现这些氧化物超导体的 Tc和相应的平均金属价电子数之间有一个经验规律,这个经验规律对氧化物超导体的元素替代以及新体系的发现有一定的指导作用。

A number of high Tc oxide superconductors are analysed in this letter. It is found that there is an empirical rule between the number of average valence electron and the Tc in these superconductors. This rule may play a guidance role in the element substitution of these: oxide superconductors and the discovery of some new system's.
