要約(英語): Heat treatment in a magnetic field is necessary to improve magnetic properties of the Fe-based amorphous magnetic materials (Fe-Si-B). In this paper, we proposed a magnetic-field annealing method with SmCo permanent magnets for the purpose of heat-treating amorphous cores in various shapes. As a basic study, for a 10 mm × 60 mm strip-shaped samples, the magnetic-field annealing was conducted in an electric furnace, and the magnetic properties before and after heat treatment were compared with those of a conventional method with an electromagnet. Magnetic measurements were performed by using a small-sized single-sheet-tester (S-SST). The results showed that the magnetic properties after heat treatment with the permanent magnets can be improved as well as those with the conventional electromagnet method. This paper clarified issues to be solved for further improvement of the proposed method with permanent magnets.
