The valence band and the transition metal core level spectra were analyzed. Several contributions from the Mn 3d, Co 3d and of extensively hybridized Mn3d-O2p and Co3d-O2p states were found in the spectral region between 2 eV and 5 eV. The core level spectra show the presence of Co4+ and Co2+ states. (C) 2014 Elsevier B.V. All rights reserved. |
