Outline of Final Research Achievements

In the present research project, we have worked on the improvement of the vector-magnet apparatus for x-ray dichroism spectroscopy, which has allowed us to perform angle-dependent x-ray magnetic circular dichroism (XMCD) experiments with higher precision than before. We have also established a methodology to investigate the electron orbital occupation in ferromagnets using this method. We have performed angle-dependent XMCD experiments on several ferromagnets such as (La,Sr)MnO3 and L10-type FePt, which are candidates for spintronics materials. We have experimentally demonstrated that, in order to explain the magnetic anisotropy of ferromagnetic thin films, one has to take into account the anisotropy of the electron-density distribution in addition to the anisotropy of the orbital magnetic moment.
