Mn 3d states in MnY (Y = S, Se, Te) have been investigated by resonant
photoemission experiments in the Mn 3p-3d excitation region. For all
compounds, a characteristic feature with three structures at 0-2.5 and
3.5 eV, and around 8 eV below the valence-band maximum is observed. A
chemical trend of the Mn 3d DOS's in MnY is interpreted by the increa
ses of a ligand to 3d charge transfer energy and/or pd hybridization f
rom MnTe to MnS.
