Superconductivity of 30.4 K and its Reemergence under Pressure in Fe1.11Se Synthesized via Ion-exchange and De-intercalation Reaction

This study reports the successful synthesis of a non-stoichiometric Fe1.11Se single crystal with a record-high superconducting onset temperature of 30.4 K via hydrothermal ion-exchange, which exhibits a unique "V"-shaped pressure evolution and a reemergent superconducting state despite containing 11% interstitial iron that typically suppresses superconductivity.
