| Outline of Final Research Achievements |
This study aims to control the magnetic anisotropy of ferromagnetic materials and manipulate the magnetic ordering through change in magnetic anisotropy by high-frequency high magnetic field that is generated with localized surface plasmon resonance of nanostructures of Au. In magnetic field dependent Faraday rotation angle of Co ferrite with nanostructures of Au, the coercive force significantly decreased around LSPR wavelength. In the magnetite particles/Au particles mixture sample, small change in magnetization was observed under laser irradiation of wavelength close to the LSPR. The former shows the possible control of magnetic anisotropy using LSPR, and the latter indicates the possible manipulation of magnetic order through the change in magnetic anisotropy.
