Abstract:FeSe-based superconductors, as an important part of the family of iron-based superconducting materials, have attracted intensive research interest in the field of condensed matter physics. The exploration and preparation of such superconducting materials is the basis for studying their physical properties. At present, the exploration of FeSe-based superconducting materials mainly focuses on intercalated materials and epitaxial single-layer FeSe films. Among them, the intercalated FeSe-based superconducting materials have unique properties and are numerous in variety. This paper introduces a series of FeSe-based high-temperature superconducting materials discovered in recent years, covering KxFe2Se2, AxNH3FeSe, LiOHFeSe and organic molecular intercalation FeSe, etc., their properties and impacts are also briefly described.
