概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
Soft magnetic materials play an important role in power electronic applications. In this project we develop soft magnetic materials with large saturation magnetization and low core losses for high frequency power electronic applications.
実験 / Experimental
the alloys were prepared by induction melting followed by melt spinning process. The chemical composition of Fe-rich alloys were measured by ICP method.
結果と考察 / Results and Discussion
Fe-enriched amorphous ribbons with a composition of Fe84.8Si0.5B9.4P3.4Cu0.8C1.1 in at. % were fabricated using an industrial-scale rapid solidification process, demonstrating excellent quality and flexibility. The composition of alloys were measured by ICP. the ribbons were annealed at different temperatures to optimize their nanostructure followed by magnetic and core loss measurements at different temperatures.
