ABSTRACT:
Rare earth-iron series permanent magnets having sufficient coercive force to be used as permanent magnets are produced by casting an ingot of molten raw material containing at least one rare earth element, at least one transition metal element and boron. The ingot can be hot worked and/or heat treated and/or otherwise processed into a permanent magnet.
