Nd等稀土元素掺杂对铁基永磁合金的磁性影响

Effect of Nd and other Rare-earth Elements on Magnetic Properties of Iron-based Permanent Magnets

本文介绍了以Nd、Tb为代表的几种稀土元素掺杂所形成的铁硼基磁体复合材料的晶体结构与磁性能,并讨论了不同稀土元素掺杂对铁基永磁合金的居里温度及矫顽力的影响,发现在铁硼磁体中适量掺杂Nd、Tb等稀土元素可适当提高其居里温度及矫顽力。

The composite crystal structure and magnetic properties of rare earth-doped-Fe-B based magnets were introduced, and the effects of different rare earth elements on the Curie temperature and coercivity of iron-based alloys was discussed. The results showed that the rare earth element doping such as Nd, Tb may be appropriate to their Curie temperature and coercivity.
