Hard-magnetic alloys of rare earth metals with 3d-metals

Abstract

The phase relations obtained from alloys of the rare-earth metals (RE) with 3d-metals are initially discussed, as well as the crystal structures and the general physical properties of the corresponding intermetallic compounds. The magnetic properties of RE-3d-compounds and the essential data of a hard-magnetic material are then summarized. The different steps in the production of RE-Co-permanent magnets are reviewed in relation to the underlying basic physical mechanisms. Finally, other possible hard-magnetic RE-3d-alloys and some general trends of physical and metallurgical investigations, necessary for the improvement of the RECo5-magnets, are outlined.
