Composition controlled synthesis of fcc-FePt nanoparticles using a modified polyol process

摘要

A low temperature synthesis method using a modified polyol process is employed to synthesize FePt nanoparticles even at 393 K. The composition could be controlled using the above process by varying the reaction conditions to obtain Fe₅₀Pt₅₀ nanoparticles at 473 K. The magnetic properties of the fcc-FePt nanoparticles indicate that they are not completely superparamagnetic in spite of the smaller particle size.
