PHOTOEMISSION FROM FE W(110)

Thin magnetized Fe/W(110) films were investigated by spin resolving ph otoelectron spectroscopy with unpolarized VUV-tight as well as by magn etic circular dichroism in photoemission using left and right circular ly polarized synchrotron radiation. The spin resolved intensities and polarization curve directly reflect the majority and minority spin cha racter of the valence bands along the Sigma direction. In contrast, th e asymmetry in the photoelectron intensities depending on the helicity of the incoming synchrotron radiation is caused by spin-orbit in comb ination with exchange interaction. By determination of the spin polari zation of photoelectrons and the magnetic circular dichroism one can, in principle, obtain complementary information about the electronic an d magnetic properties of the iron film.
