HIGH SATURATION MAGNETIZATION Fe-N MAGNETIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide high saturation magnetization Fe-N magnetic material of low cost, which exhibits saturation magnetization which is higher than or equal to that of Fe. SOLUTION: This high saturation magnetization Fe-N magnetic material is provided with a mixed phase of an α-Fe phase and a Fe16N2 phase. It is preferable that the formation ratio of the Fe16N2 phase in the mixed phase be 10-90%. This magnetic material is obtained by a method, where material powder such as iron oxide powder and metal iron powder are subjected to hydrogen reduction, nitriding is performed by using a gas containing ammonia, and the Fe16N2 phase is partially formed in the material powder.
