Magnetization Analysis by Spin-Polarized Scanning Electron Microscopy

Figure 4

Spin-SEM images of Co (0001) in same area as shown in Figure 3 as temperature was raised from 100 to 500°C. Two in-plane magnetization-component images are shown for each temperature. Between 200 and 300°C, domain structures of 2-3 um changed into structures larger than 10 um. Between 400 and 500°C, small domain structures of 2-3 um appeared inside large domains.
