METHOD FOR PRODUCING NANOPARTICLE OF NICKEL-IRON ALLOY WITH HIGH SATURATION MAGNETIZATION, AND NANOPARTICLE OF NICKEL-IRON ALLOY WITH HIGH SATURATION MAGNETIZATION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a nanoparticle of a nickel-iron alloy with high saturation magnetization, which can easily and inexpensively produce the nano-sized particle of the nickel-iron alloy with the high saturation magnetization, and to provide the nanoparticle of the nickel-iron alloy with the high saturation magnetization obtained by the method for producing the nanoparticle of the nickel-iron alloy with the high saturation magnetization.;SOLUTION: The method for producing the nanoparticle of the nickel-iron alloy with the high saturation magnetization includes forming the nanoparticle of the nickel-iron alloy by adding a reduction reaction adjuvant in which hydrazine (N₂H₄) is concomitantly used with sodium hydroxide, to a solution of a polyhydric alcohol such as ethylene glycol, which contains a nickel salt and an iron salt, and simultaneously reducing a nickel ion and an iron ion contained in the solution of the polyhydric alcohol.;COPYRIGHT: (C)2011,JPO&INPIT
