Surface magnetism of iron on W(110)

Ultrathin bcc iron films grown epitaxially on W(110) have been investigated by means of angle and spin resolving photoelectron spectroscopy. The electron spin polarization, spin resolved intensities and corresponding band structure have been experimentally investigated in dependence of the film thickness, exciting photon energy and variation of the photoelectron detection angle. Additionally, photoemission calculations for bulk iron have been performed in the framework of a relativistic one-step formalism. The comparison between measured and calculated spectra turns out to be in very good agreement for different excitation energies as well as for different angles of emission.
