在钕铁硼基永磁体中，用储量最丰富、成本最低的稀土元素Ce取代Dy和Nd是重要的，因为Dy和Nd是昂贵的、关键的稀土元素。Ce， Co共掺杂合金具有优异的高温磁性能，在T≥453 K时，其固有矫顽力最高。
Replacement of Dy and substitution of Nd in NdFeB-based permanent magnets by Ce, the most abundant and lowest cost rare earth element, is important because Dy and Nd are costly and critical rare earth elements. The Ce, Co co-doped alloys have excellent high-temperature magnetic properties with an intrinsic coercivity being the highest known for T≥ 453 K.
