Impact of RE-rich phases on magnetic properties in RE–Fe–B-sintered magnets by Tb diffusion

We investigated the effect of Tb grain boundary diffusion on the structural transformation and magnetic properties across operational temperature ranges. Through micro-structural characterization, Fm[Formula: see text]m-type and Ia[Formula: see text]-type RE-rich phases were observed, and their effe...
