Emission of spin-polarized electrons during grazing scattering of multiply charged N ions from a Fe( [formula omitted]) surface

We present spin-resolved energy spectra for electrons emitted during grazing scattering of 150 keV multicharged nitrogen ions from magnetized Fe(1 0 0) and nonmagnetic, polycrystalline Ta surfaces. For scattering from Fe we observe a substantial spin polarization parallel to the average spin polariz...

Zusammenfassung:	We present spin-resolved energy spectra for electrons emitted during grazing scattering of 150 keV multicharged nitrogen ions from magnetized Fe(1 0 0) and nonmagnetic, polycrystalline Ta surfaces. For scattering from Fe we observe a substantial spin polarization parallel to the average spin polarization of conduction band electrons. Experimental procedure, evaluation of data, and implications on concepts concerning the interaction of multicharged ions with surfaces are discussed.
