Abstract

The science and technology of conventional ferrite magnets is reviewed, including their historical evolution and models to explain their properties. Next, a survey is given of the new LaCo-type ferrite magnets, representing a breakthrough in magnetic performance. The increased performance is explained with the classical models. Increased market share of M-ferrite magnets as well as re-intensification of background research is expected.
