Process for the synthesis of FePt nanoparticles

摘要

PROBLEM TO BE SOLVED: To provide a method for producing FePt nanoparticles capable of directly synthesizing L1₀-phase FePt nanoparticles having high regularization degree and coercivity with ease.;SOLUTION: The method for producing the FePt nanoparticles comprises: a solution preparing step for preparing a solution containing iron (Fe) acetylacetonate, platinum (Pt) acetylacetonate, and a reducing agent in a mixed solvent made by mixing a first solvent consisting of triphenylbenzene or triphenylene and a second solvent consisting of at least one kind of a straight-chain hydrocarbon represented as C_nH_2n+2 (n=22 to 30) or a branched hydrocarbon; and a reacting step for obtaining the L1₀-phase FePt nanoparticles by heating the solution to no less than 360°C and reducing the same.;COPYRIGHT: (C)2008,JPO&INPIT
