PURPOSE:To obtain a permanent magnet material which is excellent in residual magnetic flux density and coercive force and has a great maximum energy product in low cost by making the rate of a rare earth element in a Ce series Misch metal a specific wt% in the composition of the permanent magnet material shown by a general formula. CONSTITUTION:A permanent magnet material shown by a general formula M1-alpha-beta-gamma-deltaAalphaXbetaZgammaCadelta has a composition that M is a Ce series mesh metal, A is one or two elements among Fe, Co, Ni and Mn, X is one or two elements among Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W and Al, Z is one or two elements among B, C, N, Si and P and 0.60<=alpha<=0.85, 0.01<=beta<=0.10, 0.01<gamma<0.15, 0<=delta<=0.05. |
