FIELD: metallurgy.
SUBSTANCE: manufacturing method of rare-earth magnets involves a stage of bringing a compacted item obtained by hot processing in order to create anisotropy in a sintered item having a rare-earth magnetic composition in contact with alloy melt with a low fusion temperature, which contains a rare-earth element.
EFFECT: increasing a coercitive force without any addition of large amount of such rare-earth elements as Dy and Tb.
