Title: An Electron Spin Polarization Detector: Spin Dependent Absorption of a Polarized Electron Beam
Published: April 01, 1981
Abstract: The exchange interaction and the spin-orbit interaction are observed to cause a spin dependence of the absorption of a polarized electron beam in the amorphous ferromagnet Ni40Fe40B20 and a W(100) single crystal respectively. The enhancement of the spin dependence, near the energy where the secondary electron yield is unity, is shown to provide a simple efficient detector of spin polarization.
