RESONANT PHOTOEMISSION-STUDY OF MN 3D ELECTRONS CONTRIBUTION TO THE PB0.92MN0.08SE VALENCE-BAND

The resonant photoemission spectroscopy was applied to investigate the valence band electronic structure of semimagnetic semiconductor Pb0.9 2Mn0.08Te crystal and to determine the contribution of Mn 3d electrons to the valence band. The set of energy distribution curves and consta nt initial states spectra were taken for hv energies in the region (40 -60 eV) close to the Mn 3p-3d transition. The electrons Mn 3d hybridiz e and contribute to the valence band electrons of the crystal and main density of states contribution appears in the energy 3.5 +/- 0.2 eV b elow the valence band edge.
