Pressure-Induced Superconductivity in BiS2-Based EuFBiS2

We measured the electrical resistivity of the BiS2-based compound EuFBiS2 under high pressure. Polycrystalline EuFBiS2 shows insulator–metal transition and pressure-induced superconductivity above 0.7 GPa. The superconducting transition temperature increases with increasing applied pressure and shows a maximum value around 8.6 K at 1.8 GPa.
