Abstract (en)
A method of producing a two-phase separation type Fe-Cr-Co series permanent magnet is disclosed, which comprises forming a rapidly solidified tape or a thin sheet from a melt having an alloy composition of Fe100 x-yCrxCoy or Fe100-x-y-zCrxCoyMz and subjecting to a heat treatment. In this case, permanent magnets having excellent magnetic properties in any direction among the longitudinal, widthwise and thickness directions can be produced by performing the heat treatment under particular conditions.
