In this paper, the physical properties of the newly discovered Fe-chalcogenide superconductors were summarized and the origin of the high transition temperature was discussed with change in both the crystal structure and magnetism.Abstract:
Here we summarize the physical properties of the newly discovered Fe-chalcogenide superconductors. The Fe-chalcogenide superconductors are of great interest because they are 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 change in both the crystal structure and magnetism. Advances in the thin-film and superconducting-wire fabrication are also described.read more
