PROBLEM TO BE SOLVED : To provide magnet powder including a Sm-Fe-N based material and arrange to be able to have a large coercive force even when the powder has a relatively large grain diameter.
SOLUTION : Magnet powder comprises a Sm-Fe-N based material; the main phases of which have an average crystal grain diameter of 1 μm or less. The ratio of the intensity of an Fe (110) peak to that of a Sm2Fe17 (303) peak measured by X-ray diffraction method is 0.01-0.80.
