Abstract

The measurement of the spinpolarization of photoelectrons from ferromagnetic semiconductors with a novel apparatus shows that the surface is magnetically not saturated even at temperatures far below the Curietemperature. In EuO the ionization threshold of the 4f 7-states depends on doping; furthermore two types of doping coexist, differing in their spinpolarization and the photoelectric yield spectrum. The surface magnetism is influenced by evaporation of a very thin metal film. EuO is an intense source of highly polarized electrons suitable for use with a pulsed high energy accelerator.
