Abstract
The dependence on primary energy, angle, and temperature of spin-polarized electron-energy-loss spectra from Ni(110) has been investigated. It is shown that the spin asymmetries are strongly energy and angle dependent. The behavior can be accounted for in a simple model in which the inelastic intensity consists of two contributions: A strongly energy- and angle-dependent dipole contribution (purely direct scattering) is superimposed on an isotropic-impact scattering mechanism, which is dominated by exchange scattering. Temperature-dependent spectra do not reveal any changes in the electronic structure between room temperature and the Curie temperature.Keywords
