摘要

The pressure (P) dependence of AC susceptibility and electrical resistivity of FeSe 0.88 and FeSe 0.5Te 0.5 has been studied. The superconducting transition temperature (T c) of FeSe 0.5Te 0.5 is found to be more sensitive to P than it is in FeSe 0.88, which is believed to arise from the strongly distorted structure. The enhancement of T c by P is mainly attributed to an increase of density of states, which implies that the superconductivity in FeSe 1-xTe x favors pairing mechanism in the context of strong-coupling BCS theory.
