Title
(EN) Magnetic material and method for producing same
(ZH) 磁性材料及其制造方法
Abstract
(EN)
The invention relates to a method for producing a magnetic material, said magnetic material consisting of a starting material that comprises a rare earth metal (SE) and at least one transition metal. The method has the following steps: hydrogenating the starting material, disproportioning the starting material, desorption, and recombination. A magnetic field is applied during at least one step such that a textured magnetic material is obtained and the formation of a texture is promoted in the magnetic material.
