Contribution of Mn 3d electrons to the valence band of Sn_0.9 Mn_0.1Te

摘要

The synchrotron radiation in the energy range between 15 and 70 eV was sued to investigate the electronic structure of the crystalline Sn_0.9 Mn_0.1Te by means of the resonant photoemission spectroscopy. Fano-type resonance has been observed in the obtained constant initial energy curves with the resonant energy 50.6 eV and antiresonant energy 49.0 eV. The energy dis- tribution 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 valence band edge.
