摘要：

Photoelectrons from ferromagnetic films of EuS and EuSe show spin polarization. The highest degree of polarization P = 0.34 ± 0.02 was obtained with EuS at a photon energy of 5.0 eV in a magnetic field of 33 kG perpendicular to the film. The usefulness of the experimental technique for the investigation of the electronic band structure in ferromagnets is demonstrated. © 1969.
