摘要:

我们研究了FeSe超导体及其相关化合物的压力效应。FeSe_(0.8)S_(0.2)的超导转变温度(Tc)随压力的变化在0.76GPa以下呈现出一个圆顶形的行为。另一方面,FeSe 0.25Te 0.75的Tc线性增加至0.99GPa。本文讨论了FeSe系统的物理压力效应和化学压力效应之间的关系。

英文摘要:

We investigated the pressure effects on the FeSe superconductor and the related compounds. Pressure dependence of superconducting transition temperature (Tc) for FeSe0.8S0.2 exhibits a dome-shaped behavior below 0.76 GPa. On the other hand, the Tc of FeSe0.25Te0.75 linearly increases up to 0.99 GPa. Here we discuss the relation between the physical pressure effects and the chemical pressure effects on the FeSe system.
