An Electron Spin Polarization Detector: Spin Dependent Absorption of a Polarized Electron Beam
Robert Celotta, Daniel T. Pierce, H Siegmann, John Unguris
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.
