| dc.description | The valence-band electronic structure of a crystalline thin film of has been investigated using angle-resolved photoemission. The observed valence-band structure has a substantial surface contribution and is strongly influenced by the surface conditions. Surface contamination and disorder attenuate the emission from a Mn-3d-derived state at a binding energy of 3.3 eV. This state was found to be localized at the surface with dispersion only in the plane of the surface and exhibited a strong intensity dependence on emission angle. On the basis of a simple LMTO-ASA bulk band calculation, it is clear that this state does not fall within a bulk band gap. We have therefore identified this Mn-3d-derived state at 3.3 eV below as a surface resonance. |
