Abstract
We report a spin-resolved inverse photoemission study of the electronic structure of Fe/Au(100) thin films, concentrating on states at the center of the surface Brillouin zone and film thicknesses in the monolayer regime. We identify states with minority-spin character 0.7 eV above the Fermi level, confirming previous tentative assignments based upon spin-integrated studies. However, a feature previously assigned to a quantum-well state is found to be exchange split by only \ensuremath{\simeq}200 meV, to small to originate from Fe-derived states, but in line with self-consistent band-structure calculations that predict an Au-derived interface state.
