| 简介 |
Provided are : a rare earth permanent magnet in which the magnetic properties of the permanent magnet are improved by appropriately conducting magnetic field orientation; and a rare earth permanent magnet production method. Magnet material is pulverized into magnet powder, and a compound (12) is produced by mixing the pulverized magnet powder with a binder. A green sheet (14) formed in a sheet form on a supporting substrate (13) is produced by hot melt molding the compound (12) that was produced. Then, the green sheet (14) that was formed is softened by heating, and magnetic field orientation is conducted by applying a magnetic field to the heated green sheet (14). Permanent magnets (1) are then produced by sintering the green sheet (14) after magnetic field orientation. |
