摘要:
本文提出Sanderson电负性均衡值Seq可作为氧化物超导电性的新的经验判据. 判据指出:Tc在10K以上的氧化物超导体的Seq值都在1.94至2.40之间,Tc在78K以上的氧化物高温超导体的Seq值集中在2.12至2.34之间.该判据几乎适用于一切氧化物超导体.
关键词: 氧化物超导体, Sanderson电负性均衡值
Abstract:
In this article it is suggested that the Sanderson's equalized electronegativity, Seq, can be used as a new empirical criterion for superconductivity of oxides. The criterion shows that the Seq values are between 1.94 and 2.40 for oxide superconductors with Tc above 10K; the Seq values concentrate in a very narrow range from 2.12 to 2.34 for the high-Tc superconductors with Tc above 78K. This criterion can be applied to almost all the oxide superconductors.
Key words: Oxide superconductors, Sandersons equalized electronegativity
