Abstract
  • Resonant photoemission spectroscopy data from Cd1-xMnxTe single crystals are presented. A strong resonant behavior, related to the Raman-Auger decay channel arising from the creation of the Mn 2p core hole, is detected for states in the valence-band region at the Mn 2p-->3d absorption threshold. The transition from the resonating Raman-Auger to the weak, normal Auger emission is shown to occur well above the main absorption edge. This effect is ascribed to the presence of a manifold of localized states arising from the Mn 2p-->3d Coulomb and exchange interaction, which prevents the delocalization in the intermediate state of the autoionization process.
