| Outline of Final Research Achievements |
To understand local structures around magnetic elements, we measured X-ray fluorescence holograms of Co:TiO2 thin film, Mn:ZnSnAs2 thin film and GeMnTe thin film. In Co:TiO2 thin film, we discovered suboxide clusters around Co. The crystal structure of ZnSnAs2 thin film was sphalerite-type, and the As sublattice was largely distorted. Moreover, the local structure around Ge in GeMnTe thin film, reflecting rhombohedral GeTe structure, had lower symmetry than that around Mn.
