Iron-chalcogenide superconductor FeSe has attracted due to the highly enhanced superconductivity observed in monolayer films on SrTiO₃ (STO) resulting from interface effects. We have worked on the realization of the interface-enhanced superconductivity using pulsed laser deposition, and realized the superconductivity in ultrathin films thicker than 2 nm. In this study, we investigated the superconducting properties in magnetic fields up to 19 T.
