Zusammenfassung:	PURPOSE:To produce fine powder of ferromagnetic metal which is easily and highly dispersed by ultra-pulverizing mechanically the ferromagnetic metallic powder obtd. by reduction in a reducing atmosphere in a dispersion medium inert with said powder. CONSTITUTION:The ferromagnetic powder of the iron obtd. by reduction in a reducing atmosphere or the alloy compsn. consisting principally of the iron and contg. Ni, Co, Mn, etc. is dipped in an org. solvent such as toluene, xylene or the like without being exposed to air after reduction and thereafter the powder is subjected to a high dispersion treatment mechanically to
