| Outline of Final Research Achievements |
We have investigated the controllability of the exchange interaction by external fields in magnetic impurities and magnetic interfaces. We developed the new instruments for magnetic spectroscopy measuring the spin and orbital magnetic moments. We discussed two topics: (i) the doner-exchange interaction through the oxygen vacancies in magnetic oxide semiconductors and (ii) the mechanism of perpendicular magnetic anisotropy at the interface between ferromagnetic alloys and MgO. We found that the Fe-O chemical bonding becomes an essential role, which brings the control of anisotropy by the external fields.
