Enhanced Coercivity and Tb Distribution Optimization of Sintered Nd-Fe-B Magnets by TbF<sub>3</sub> Grain Boundary Diffusion Facilitated by Ga

Enhanced Coercivity and Tb Distribution Optimization of Sintered Nd-Fe-B Magnets by TbF<sub>3</sub> Grain Boundary Diffusion Facilitated by Ga

The grain boundary diffusion process employing a mixed diffusion source, comprising heavy rare-earth elements and low-melting metals, significantly enhances the coercivity (H<sub>cj</sub>) of sintered Nd-Fe-B magnets. In the present study, Tb and Ga were deposited onto the surface of Nd-...
