description: The given work is devoted to the study of polarization of inelastic electron scattering on a PbS crystal. It is known that the spin-orbit interaction energy is directly proportional to the atomic number of the element, hence, high polarization of Auger electrons is observed in PbS. Measurements were made by spin-resolved Auger-spectroscopy in the energy range of 50-120 eV at incidence angles from 35Ð¾Â to 55Ð¾. The high polarization of the Pb-N7O45O45Â Auger-peak up to 16% and the polarization angle dependences were found. The polarization energy spectra at different incidence angles of the primary beam show a change in the polarization sign at 40o. The absence of polarization at the peak maximum and polarization of different signs at the left and right falls were detected. Thus, electron scattering with the participation of Pb-N7O45O45Â Auger junction causes strong polarization of the whole peak up to 5%. Due to the change of polarization sign during sample rotation and intense spin splitting, the studied material can be used for creating spintronics devices such as electron polarizers.
