Abstract
Spin polarization of electron-excited secondary electrons from a permalloy polycrystal has been measured as a function of incident beam energy, E i, from 200 eV–2 keV. A spin polarization of 6% at E i=200 eV increases with E i and reaches a saturation value of 11% at E i=1.1 keV. This polarization value remains constant up to E i=2 keV. An intrinsic decrease in surface magnetization is proposed as a possible cause of this feature.Keywords
