Abstract
A feature at a binding energy of similar to 2.5eV which has not previously been discussed in the literature is observed in the photoemission spectra of the valence band of La1-xSrxMnO3 single crystals. To reveal the origin of this feature measurements of resonant photoemission on La1-xSrxMnO3 were performed as well as absorption spectra at the La N and Mn L-2,L-3 edges at liquid nitrogen and room temperatures. Only for Mn L edge we observed a clear resonance for a binding energy corresponding to the feature of interest. Comparison with the calculated density of states led to the conclusion that the feature corresponds to Mn t(2g) states.
