摘要：

Inelastic exchange scattering of low-energy electrons off disordered localized Cr3+ magnetic moments at a Cr2O3 surface is studied by spin-polarized electron-energy-loss spectroscopy. The excitations from a spin-quartet ground state to doublet states via exchange scattering give rise to sharp energy-loss lines, which are predominantly spin flip, and provide an efficient electron depolarization mechanism. © 1990 The American Physical Society.
