PURPOSE:To provide a sintered permanent magnet consisting of hard magnetic material using permanent magnetic powder, having high coercive force, especially of the sintered body of high coercive force permanent magnetic powder. CONSTITUTION:Composition equation is (T1-XMX)ZR1-Z, with 0.01<=x<=0.28 and 0.35<=z<=0.89. However, T is Fe and/or Co, M is one or more kinds of combinations selected from B, Si or C, and R is Nd and/or Pr, in addition, one or more kinds of combinations selected from La, Ce, Sm, Tb, Ho, Dy, or Y. Made of a sintered body of high coercive force permanent magnet power, having crystal grain of the size of amorphous recrystallization. |
