摘      要：Annealing has been widely recognized as a crucial approach to modify the microstructure and enhance the coercivity of Nd–Fe–B magnets. However, in the context of Nd–Y–Ce–Fe–B magnets with multiple rare earths(REs) exhibiting different diffusion behaviors, annealing effects on the magnetic properties become more complicated and remain unknown.
