Summary

Sm-Co magnets offer the largest energy product ((BH)max) of the order of 20 MGOe. As a consequence of cost and availability considerations samarium and cobalt are not the most desirable constituents for the large scale use and in 1970 light rare earth-iron materials began to be investigated as a potential alternative to the Sm-Co alloy. This led to the development of Nd-Fe-B magnetic materials. The advent of this material having excellent magnetic properties and potential economic advantages has initiated a new period in permanent magnet technology. The interest in these materials stem from the wide range of materials available, including powder product for sintered magnet applications.
