Abstract
The present disclosure discloses a method for the magnetism stabilizing treatment of a permanent magnet material. The method can include the following steps: providing a permanent magnet material having a positive temperature coefficient of coercivity; magnetizing the permanent magnet material at a temperature Twith a range of −200 degree centigrades to 200 degree centigrades; and performing a magnetism stabilizing treatment towards the permanent magnet material with temperature decreased in a range of the temperature Tto a temperature T, or at the temperature T.
