| Outline of Final Research Achievements |
Fluorescence-yield depth-resolved X-ray absorption spectroscopy (XAS) technique has been developed, in which a series of XAS data with different probing depths is obtained by collecting the fluorescent X ray at different angles, which is emitted after absorption of soft X ray, in order to observe depth-resolved information on the electronic state and structure at the ferroelectric/ferromagnetic interface.
By adopting the developed technique for the interface between ferroelectric BaTiO3 and ferromagnetic Fe, it has been revealed that Fe oxides exist at the interface, and that new electric-field effect is induced by intentionally inserting Fe oxides at the interface.
