Abstract
Since the 1960s most of the developments of permanent magnetic materials have been done on the improvement of the magnetic properties. The search for new materials has been shifted from shape anisotropy to crystal anisotropy. New hard magnetic materials based on cobalt rare-earth intermetallic compounds exhibit a considerably higher coercive force and remanence than the traditional Alnico-compounds, hardmagnetic ferrites and Pt-Co magnets. Because of their low content of cobalt the ductile Fe-Cr-Co and Mn-Al-C magnets gain an increasing importance.
