The present invention provides a permanent magnet and a method for producing a permanent magnet, in which magnet powder after pulverization is heated to regenerate the surface of magnet particles and improve magnetic performance. A coarsely pulverized magnet powder is obtained by M- (OR) x (wherein M is V, Mo, Zr, Ta, Ti, W or Nb, and R is an alkyl group having 2 to 6 carbon atoms). The organic metal compound may be linear or branched, and x is an arbitrary integer. Adhere. Thereafter, the dried magnet powder is held at 600 ° C. to 1000 ° C. for several hours in a low oxygen atmosphere to regenerate each magnet particle constituting the magnet powder 43. Further, the regenerated magnet powder is molded and fired at 800 ° C. to 1180 ° C. to produce the permanent magnet 1. [Selection] Figure 5 |
