Abstract

A simple technique to synthesize composition and size-controlled cubic FeCo particles, ranging in size from a few hundred to tens of nanometers at 403 k within one hour using a modified polyol process was investigated. The metal salts were dissolved in liquid polyol under an inert atmosphere and heated to elevated temperatures to obtain fine metal or alloy nanoparticles. The black precipitate obtained was recovered from the polyol, and washed and stored in ethanol. X-ray fluorescence (XRF) analysis was carried out to determine the final composition of the powders. The hyperfine field of the ordered FeCo was found to be lower than the disordered FeCo, with the maximum decrease at the equiatomic composition.
