A simulation of electron scattering in magnetic materials

A new simulation model is proposed to calculate the electron scattering in magnetic materials. It takes into account not only the three-dimensional el ectron trajectory. but also the electron spin transport along the trajector y. The mechanisms considered in the magnetic materials are the Lorentz forc e, the spin-orbit interaction. and the secondary electron generation. The b and structure of the outer-shell electrons in the material is considered in the cascade process of low-energy secondary electron generation. The calcu lated energy dependence of the spin-polarization shows a reasonable agreeme nt with the experimental value.
