Outline of Final Research Achievements

We have investigated precise measurements of orbital magnetic moments at the interfaces. We developed novel x-ray magnetic spectrometry which enables the measurements under external fields. We clarified the mechanism of perpendicular magnetic anisotropy in Co/Pd interface and we succeeded in the detection of perpendicular magnetism in non-magnetic Cu. Further, we succeeded in the manipulation of orbital moments in strained Ni under external electric fields. These results contribute to the novel researches of spin-orbitronics.
