This invention discloses a samarium-based rare-earth permanent magnet bulk material, its preparation method, and its application. (The last part, "ThMn," appears to be an incomplete sentence or fragment and is left untranslated.) 12 A uniform metallic T coating is formed on the surface of the magnetic powder. The composite magnetic powder is then oriented, pressed into blocks, and heat-treated to create a double-layered non-magnetic shell around the grains. This shell hinders domain movement, effectively improving the material's coercivity. Furthermore, compared to doping or melting, the coating process requires less T and allows for more precise control, preventing excessive T from entering the crystal lattice and negatively impacting the material's intrinsic magnetic properties, thus significantly improving the coercivity of ThMn. 12 Density and overall performance of rare earth permanent magnets.
