In the present work, microwave-assisted chemical reduction route has been explored for the direct synthesis of fct LIo-phase of Fe-Pt nanoparticles. Effects of microwave power and irradiation time on the growth process were investigated. Using this facile and high yield technique we could tune particle size from 7 to 17 nm. The as-prepared FePt were found to be sensitive to the microwave irradiation power, while influence of exposure time was insignificant. The hysteresis measurements were performed at room temperature (300 K) to study magnetic properties of as-synthesized Fe-Pt as a function of crystallize size. The coercivity and saturation magnetization was observed to be decrease with diminishing for direct synthesis of metal alloys.
