摘要
We report on the emission of spin-polarized electrons during grazing and oblique impact of 2-100 keV H+, He+, Ne+, and Ar+ ions upon a magnetized Fe(100) surface. A combined analysis of spin state and energy of emitted electrons elucidates processes occurring in inelastic ion-surface scattering such as electron cascading or plasmon-assisted electron emission and indicates a significant enhancement of the spin moment at the topmost layer of Fe(100).
