Gradient Nd—Fe—B magnet and a method of production
A gradient NdFeB magnet includes an NdFeB magnet block extending along a magnetization direction and having a plurality of surfaces perpendicular to the magnetization direction. A first film, is disposed on one of the surfaces. A second film is disposed on another one of the surfaces, opposite of the one of the surfaces. The first film and the second film are diffused into the NdFeB magnet block dividing the NdFeB magnet block into an edge region, a transition region, and a central region along a plane perpendicular to the magnetization direction wherein the edge region has a coercivity that remains constant in a direction perpendicular to the magnetization direction, and the coercivity, along said magnetization direction, gradually decreases from the one of the surfaces and the another one of the surfaces towards a point located therebetween. A method of making the gradient NdFeB magnet is disclosed herein.
