A review of Fe-chalcogenide superconductors: the simplest Fe-based superconductor

Abstract

Here we summarize the physical properties of the newly discovered Fe-chalcogenide superconductors. The Fe-chalcogenide superconductors attract us as the simplest Fe-based superconductors. Furthermore, Fe chalcogenides show a huge pressure effect on their superconducting properties. The origin of the high transition temperature was discussed with both the change in crystal structure and magnetism. The progress on the thin-film and superconducting-wire fabrications are also described.

A review article of Fe-chalcogenide superconductor submitted to J. Phys. Soc. Jpn. 51 pages, 54 figures including reprinted from the published papers
