Magnetocrystalline anisotropy of partially ordered Fe-Pt nanoparticles directly synthesized with microwave-polyol method

Abstract

We report direct synthesis of chemically ordered Fe-Pt nanoparticles using microwave irradiation during polyol reaction at 250/spl deg/C without any post-synthesis treatments. Mo/spl uml/ssbauer analysis exhibits the Fe-Pt nanoparticles having partially ordered L1/sub 0/ structure, and the fraction of Fe atoms in the chemically ordered L1/sub 0/ structure… (More)
