Abstract: PURPOSE:To provide a rare earth-transition metal-nitrogen magnetic material which is made of coarse particles, can exert a large coercive force, and has an excellent oxidation resistance and temperature characteristic. CONSTITUTION:A magnetic material is expressed by a general expression, RalphaFe(100-alpha-beta-gamma)MnbetaNgamma(where, R is at least one kind of rare-earth element and alpha, beta, and gamma represent atomic % and satisfy relations, 3 =10mum.
