SYNCHROTRON-RADIATION PHOTOEMISSION-STUDIES OF FE 3D STATES IN CD1-XFEXSE

The angle integrated resonant photoemission measurements of Cd1-xFexSe were performed for different Fe concentrations (x = 0.00, 0.07, 0.14) in the photon energy range between 30 eV and 70 eV using synchrotron radiation. The ternary compound valence band photoemission spectra sho w, in comparison to the CdSe results, two additional structures, whose intensity depends on Fe content, which were assigned to Fe 3d states of e symmetry with spin up and down, respectively. The hybridization o f the t(2) component of the 3d electrons of Fe in the valence band is discussed.
