Abstract

FePt nanorods and nanowires have been synthesized by the reduction ofPt(acac)2 and the thermaldecomposition of Fe(CO)5 in the presence of solvents/surfactants by simply controlling the sequence of addition ofsurfactants. The as-synthesized FePt nanorods and nanowires have a face centered cubicstructure with average diameter of 3 nm. Length of nanorods and nanowires can beadjusted in the range of 15–150 nm by varying reaction parameters. NanocrystallineL10 FePt phase with coercivity up to 24 kOe was obtained after heat treatments.
