RARE EARTH PERMANENT MAGNET AND METHOD FOR MANUFACTURING RARE EARTH PERMANENT MAGNET

摘要

There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of achieving improvement of magnetic properties by optimizing magnetic field orientation. In the method, magnet material is milled into magnet powder. Next, the magnet powder and a binder are mixed to obtain a mixture. Next, the thus prepared mixture is formed into long-sheet-like shape so as to obtain a green sheet 13. Before the thus formed green sheet 13 dries, magnetic field is applied in an in-plane and transverse direction or an in-plane and machine direction of the green sheet for magnetic field orientation. Thereby, a permanent magnet 1 is obtained.
