Abstract
- Fe L2,3-edge x-ray absorption spectroscopy has been used to study the electronic structure of FeSe1-xTex chalcogenides. The spectra are quite similar to those for the metallic Fe and Fe-based pnictides, consistent with weak correlation effects in the chalcogenides. A systematic change in the experimental spectra with Te substitution is observed and well reproduced by cluster calculations. A combined experimental and theoretical analysis reveals decreased hybridization of Fe 3d and chalcogen p states with increasing Te concentration, which could be important for the superconductivity and magnetism of the chalcogenides.
