Abstract

A full analytic approach to the elastic low energy electron diffraction (LEED) from magnetic surfaces is presented. In the approach the dynamical surface scattering LEED and exchange potentials are derived from the effective scattering potentials of a free atom. The LEED and exchange scattering amplitudes obtained in the paper are given in their analytical form and thus polarization effects are analyzed. The formula obtained for the polarization of electrons scattered from magnetic surfaces leads in a special kinematic case to that obtained by Saldana and Helman [7].
