Abstract

Selon l'invention, dans un procédé de fabrication de particules magnétiques métalliques nanocomposites contenant des particules de FePt et des particules Fe, un sel de Fe et un sel de Pt sont dissous dans un solvant contenant un agent tensio-actif en surface, et un agent réducteur est ajouté à une température qui est supérieure ou égale à une température de réduction d'ions Fe qui constituent le sel de Fe. De cette façon, des particules de FePt sont synthétisées, et en même temps, des particules Fe sont déposées sur une partie des particules de FePt servant de noyau.
