Outline of Final Research Achievements

Schattschneider et al. reported that the same magnetic signals as those utilized in x-ray synchrotron facility can realize by using scanning transmission electron microscope equipped with electron energy loss spectroscopy. Because the signal intensities of usual instruments decreased significantly as the sample thickness increased, we could not utilized the magnetic signals to local magnetic analysis on real materials, however. In the present research, we showed that we could keep the magnetic signal intensities of relatively thick samples when we used an ultra-high voltage electron microscope with high kinetic energy electro as a probe, enabling us to acquire a quantitative magnetic signal from a thin film of iron nano particles. When we carefully fixed the measurement conditions with a guide of theoretical calculation of magnetic signals, we quantitatively observed the anisotropic magnetic signal intensities reflecting the magneto crystalline anisotropy of cobalt.
