Abstract

When electrons interact with a ferromagnet, their spin polarization vector is expected to move, depending on the magnetization of the ferromagnetic material. This spin motion, consisting of an azimuthal precession and a polar rotation about the magnetization direction, is measured. The precession of the spin polarization vector generates a torque on magnetization that turns out to be large with low-energy electrons. This makes injection as well as reflection of spin-polarized electrons an attractive alternative concept for magnetization switching.

Farago [Faraday rotation of electron spin polarization, in J. Phys. B 4, 954 (1971)] can be neglected. As is shown in Sect 2.4, elastic exchange scattering can be of only minor importance in our experiments
