Crystalline FeCo alloys (Fe64Co36, Fe59Co41, and Fe37Co63,) nanoparticles in diameter of 5-12 nm were synthesized by reduction of FeCl3 and CoCl2 with hydrazine under ultrasonic wave, which is a simple, low-cost, surfactant-free route, and may stimulate technological interests. As-synthesized Fe59Co41 nanocrystallite shows excellent soft magnetic behavior with high saturation magnetization up to 216.2 emu/g that is comparable with that of bulk Fe and Fe60Co40 alloy, and could have applications in catalysis, biotechnology, and magnetic storage devices.
