Abstract
The magnetic domain images in the spin-polarized scanning electron microscope are studied using a Monte Carlo simulation of electron scattering considering the spin direction of the generated secondary electrons. The variations of the spin polarization of secondary electrons are calculated when the electron probe scans across the magnetic domain boundary of an iron sample. We analyze the primary electron energy and the incident angle dependences of the spatial resolution of the magnetic domain images from the point of view of electron scattering. The shift of the boundary images from the actual magnetic domain boundary is also studied.
