Spin-dependent elastic and inelastic electron scattering from magnetic surfaces (invited)

Abstract
Results from scattering experiments, using a polarized electron beam combined with polarization analysis, are presented and discussed. There is no evidence of depolarization in quasielastic scattering for the systems studied [Ni(110), Ni(110)O(2×1), paramagnetic Ni(110), Pt(111), graphite]. In inelastic scattering from graphite for small energy losses the depolarization is found to be weak, whereas for ferromagnetic Fe and Ni surfaces large spin-flip contributions have been reported for small energy losses.
