Abstract
Publisher Summary This chapter describes the rich variety of spin, dependent phenomena in various areas of solid state and surface physics. Spin–polarized (SP) electrons seemed an elusive rarity, and the effects of exchange and spin orbit coupling appeared to be a small, mostly negligible correction to the dominant effects produced by the Coulomb field of the electrons. The experimental techniques used in the production of spin–polarized electron beams, measurement of SP, and various types of experiments with polarized electrons, such as photo or field emission of electrons are discussed. SP of the total photoelectron current versus photon energy is graphically represented. Magnetism in metals, magnetism in systems with localized magnetic moments, and the symmetry of electronic states is also reviewed. The spin dependence of the elastic scattering of the electrons from solids is performed by spin-polarized LEED (SPLEED) experiments. SP photoemission can be used as a surface magnetometer to monitor surface segregation and chemical reactions at the surface. Surface magnetization curves are obtained with the external magnetic field applied parallel or perpendicular to the surface.
