Pressure-temperature phase diagrams of FeSe$_{1-x}$S$_{x}$ superconductor

ORAL

Abstract

The pressure dependence of the superconducting, magnetic and structural transition temperatures and of the upper critical field were studied on sulfur-doped single crystalline FeSe. Both interplane and inplane resistance were measured under hydrostatic pressures up to 1.8 GPa with magnetic fields parallel to tetragonal $c$-axis. We will present the pressure-temperature phase diagrams of FeSe$_{1-x}$S$_{x}$. Different doping will be compared and discussed, specifically in the context of potential chemical pressure effects.
