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 electron trajectory, but also the electron spin transport along the trajectory. The mechanisms considered in the magnetic materials are the Lorentz force, the spin-orbit interaction, and the secondary electron generation. The band structure of the outer-shell electrons in the material is considered in the cascade process of low-energy secondary electron generation. The calculated energy dependence of the spin-polarization shows a reasonable agreement with the experimental value.
