Magnetic Material, Iron Core, and Rotating Electric Machine

Abstract

A magnetic material includes body-centered tetragonal (bct) crystal including iron and nitrogen, in which a molar ratio of iron to nitrogen in the crystal exceeds 8. An iron core includes soft magnetic steel sheets stacked together, in which a part or the entirety of the soft magnetic steel sheets is formed of the magnetic material which includes body-centered tetragonal (bct) crystal including iron and nitrogen and has a molar ratio of iron to nitrogen in the crystal exceeds 8. A rotating electric machine includes an iron core including soft magnetic steel sheets stacked together, in which a part or the entirety of the soft magnetic steel sheets is formed of the magnetic material which includes body-centered tetragonal (bct) crystal including iron and nitrogen and has a molar ratio of iron to nitrogen in the crystal exceeds 8.
