  • The low coercivity in Nd-Fe-B-based magnets, which is limited to around 20% of the anisotropy field (HA) of the main phase, is a bottleneck for their usage at elevated temperatures. Herein, we overcome the limit and demonstrate a coercivity of 40% HA by tuning the magnetism of grain boundaries, enabling their applications at elevated temperatures.
