摘要

Valence-band photoemission and S L X-ray emission spectroscopies have been performed for CuIr2S4 in order to investigate the electronic structure of the valence band. A structure around 1 eV below the Fermi level in the photoemission spectrum consists of Ir 5d as well as S 3p by taking into account its photon-energy dependent intensity. The S L-2.3 emission spectrum also shows a structure around 1 eV below the Fermi level, indicating that the state around I eV has the d-like or s-like character. These results indicate that S 3p has contribution to the electronic states near the Fermi level to some extent. and that the hybridization of Ir 5d with S 3p is important in understanding the electronic property of CuIr2S4.
