Abstract

Electrons with the spin polarization vector perpendicular to the magnetization direction are spin analyzed after reflection at a ferromagnetic surface. The spin polarization precesses around the magnetization and simultaneously the angle between spin polarization and magnetization is changed. This spin motion is explained by the existence of a gap in the electronic band structure of the ferromagnet.
