Epitaxial HCP(0 0 0 1) cobalt films on W(1 1 0) have been analyzed with linearly polarized synchrotron radiation in valence band photoemission (hv < 25 eV). For some photon energies the spectra show huge photoelectron intensity differences (i.e.. MLDAD effects) in the Co 3d valence band, when magnetizing the cobalt film remanently in opposite directions. The origin as well as the energy dependence of MLDAD is analyzed with respect to a fully relativistic band structure calculation including spin-orbit and exchange interaction.
