CONTRIBUTION OF MN 3D ELECTRONS TO THE VALENCE-BAND OF SN0.9MN0.1TE

The synchrotron radiation in the energy range between 15 and 70 eV was used to investigate the electronic structure of the crystalline Sn0.9 Mn0.1Te by means of the resonant photoemission spectroscopy. Fano-type resonance has been observed in the obtained constant initial energy c urves with the resonant energy 50.6 eV and antiresonant energy 49.0 eV . The energy distribution curves taken at photon energies close to the Mn 3p-3d transitions allow us to conclude that Mn atoms contribute to the valence band mainly at energies of 4.0 eV and 7.8 eV below the va lence band edge.
