PURPOSE:To provide the method for manufacturing a rare earth bond magnet which not only exhibits an excellent magnetic performance and a nice tempera ture characteristic though it does not contain hydrogen, but which has a suffi cient heat resistance. CONSTITUTION:At least one of Sn, Zn, Pb, In, Al, and Mg is added and mixed into alloy powder which is composed mainly of rare earth metal (R), Fe, N and/or C that contains a Th, Mn12-type compound as a main phase. This mixed power is molded by compression and is heat-treated at 100-600 deg.C. |
