Abstract
Mn 3d states in Y (Y=S,Se,Te) have been investigated using resonant synchrotron-radiation photoemission at the Mn 3p-3d threshold. We observe chemical trends due to anion substitution for the main Mn 3d photoemission feature at 3.5, 3.6, and 3.8 eV below the valence-band maximum as well as for the d(↑)-d(↓) exchange splitting for S, Se, and Te, respectively. The size of relaxation effects associated with the resonant-photoemission process is derived. Valence-band offsets of 0.3 eV are found between the semimagnetic Zn compounds and their parent binary alloys.
