Problems of implementing SEMPA in experiments
- 53 Downloads
A Mott analyzer of the spin polarization of secondary electrons was installed in a conventional scanning electron microscope (SEM). It can be used to study the magnetic states of the surfaces of ferromagnetic objects. The first results of experiments using scanning electron microscopy with analysis of the spin directions to obtain images with magnetic contrast are presented. Problems connected with the implementation of this procedure in the case of a conventional SEM with a relatively low vacuum are discussed, and factors affecting the choice of optimal experimental conditions are analyzed.
