Effects of pressure-induced phase transitions on superconductivity in the single crystal Fe1.02Se

Abstract

The temperature dependence of the ac susceptibility for single-crystalline Fe1.02Se has been measured at high pressures to 6.7 GPa. The superconducting transition temperature Tc displays a large increase from 7 K to 30 K in the two-phase region at 0.5 - 1 GPa. Further increase in pressure results in the decrease of Tc. The destruction of superconductivity near 7 GPa is presumably related to a structural transition from orthorhombic to hexagonal. .
