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.

Abstract: A soft magnetic iron alloy sheet has a saturation magnetic flux density comparable to that of Permendur, with the same iron loss as electromagnetic pure iron, and a lower cost than Permendur. The soft magnetic iron alloy sheet includes, as a chemical composition, 30 at % or less of Co, 0.1 at % or more and 11 at % or less of N, and 1.2 at % or less of vanadium, with the remainder being Fe and impurities. In a thickness direction of the soft magnetic iron alloy sheet, a surface layer region has an average nitrogen concentration of 1 at % or more and 15 at % or less and an internal region has a lower average nitrogen concentration than the surface layer region. In the surface layer region, a thickness is 1% or more and 30% or less from both main surfaces of the sheet and iron-nitride martensite having a tetragonal structure is formed.

Abstract: The present invention provides a soft magnetic iron sheet exhibiting a high saturation magnetic flux density and a low iron loss as compared with an electromagnetic pure iron sheet, a method for producing the soft magnetic iron sheet, and, an iron core and a dynamo-electric machine, each using the soft magnetic iron sheet. The soft magnetic iron sheet according to the present invention includes: iron as a main component; and nitrogen, in which the soft magnetic iron sheet includes, along a thickness direction of the soft magnetic iron sheet: a high nitrogen concentration layer having a nitrogen concentration of 2 at. % to 11 at.
