Outline of Final Research Achievements |
In this research project, we focused on the high-frequency electromagnetic wave resonance phenomenon in the orthorhombic iron oxide, and promoted the research with the aim of realizing high frequency electromagnetic wave absorption and rotation property. The dynamics of magnetization in resonance was investigated by analyzing the absorption spectrum. The electromagnetic rotation was observed in the sample where the magnetization direction was aligned in one direction. In addition, we clarified the origin of the high resonance frequency of this material and realized further magnetic anisotropy field improvement by metal substitution.
