Abstract
A scanning electron microscope includes a spin detector configured to measure spin polarization of a secondary electron emitted from a sample, and an analysis device configured to analyze measurement data of the spin detector. The analysis device determines a width of a region where the secondary electron spin polarization locally changes in the measurement data. The analysis device further evaluates a strain in the sample based on the width of the region. With a configuration of the scanning electron microscope, it is possible to perform analysis of a strain in a magnetic material with high accuracy.
