Abstract
Although pairing mechanism in unconventional superconductors is still an open question, the density of states at the Fermi level is considered to be one of the factors affecting the superconducting transition temperature. Herein, we report on Fe-57-Mossbauer studies of beta-FeSe, FeSe Te-0.5 (0.5), and Rb Fe-0.8 Se-1.6 (2) superconductors as well as two intercalate products consisting of FeSe layers and a lithium-containing molecular spacer in between. In these materials, the hyperfine parameters of Fe-57 are directly related to the 3d-electron density on Fe atoms and show strong correlation with superconducting properties.
