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

V. G. Tissen, E. G. Ponyatovskii, M. V. Nefedova +2

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 di…
