Method of producing precipitate of rare earth ferromagnetic alloy
 An aqueous solution containing reducing agent such as potassium borohydride or sodium borohydride is added with another solution containing salt of an iron-triads-group element and salt of a rare earth element to conduct reaction to effect reduction to the iron-triads-group metal and the rare earth metal to thereby produce fine powder of rare earth magnet composed of alloy of the iron-triads-group metal and the rare earth metal.
