Direct synthesis of L10 type Fe-Pt nanoparticles using microwave-polyol method

We report the synthesis of Fe-Pt nanoparticles with microwave irradiation during polyol-reduction reaction. Chemically ordered Fe-Pt nanoparticles with L10 structure are fabricated at 250 DGC using a microwave-polyol method without any post-synthesis treatments. Mossbauer analyses reveal the nanopar...

Zusammenfassung:	We report the synthesis of Fe-Pt nanoparticles with microwave irradiation during polyol-reduction reaction. Chemically ordered Fe-Pt nanoparticles with L10 structure are fabricated at 250 DGC using a microwave-polyol method without any post-synthesis treatments. Mossbauer analyses reveal the nanoparticles have partially ordered Ll o structure. The partially ordered Fe-Pt nanoparticles exhibit coercivity of 3.4 kOe, saturation magnetization of 49 emu/g, and anisotropy field of 83 We at room temperature.
