Outline of Final Research Achievements

In this study, we aimed to develope an X-ray ferromagnetic resonance (XFMR) microscope to performe three-dimensional analysis of magnetic properties of nano-structured magnetic materials. This technique realizes quantitative analysis of three-dimensional spatial distribution of important magnetic parameters (anisotropy field, saturation magnetization, and magnetic dumping constant) in nano-structured magnetic materials. We examined elemental technologies and achieved some positive results for the future realization of an XFMR microscope; for example, improvement of measurement efficiency with use of a machine learing technique.
