An RTB-based permanent magnet having excellent magnetization characteristics is provided. M- (OR) x (wherein M is at least one of Al, Cu, Zr, Nb, Hf, and Co) with respect to the fine powder of the pulverized RTB-based magnet. R is an alkyl group having 2 to 6 carbon atoms, which may be linear or branched. X is an arbitrary integer.) An organometallic compound solution added with an organometallic compound represented by In addition, the organometallic compound is uniformly attached to the surface of the magnet particles. Thereafter, the green compact is subjected to calcination treatment in hydrogen by holding it in a hydrogen atmosphere at 200 ° C. to 900 ° C. for several hours. Then, the permanent magnet 1 is manufactured by baking at 800 to 1180 degreeC. [Selection] Figure 3 |
