In this work, the core-shell FePt@Fe3O4 nanowires and nanoparticles as a new hard-soft composite magnetic materials were synthetized by reduction of platinum acetyl acetonate and iron pentacarbonyl together in the presence of oleic acid and oleyl amine stabilizers by polyol process. As-synthesized FePt nanowires and nanoparticles with 0.5-3 nm Fe3O4 shell were preparated by controlled addition of excess of Fe (CO)5 into the reaction mixture and air oxidation. The phase analysis, structure, and magnetic properties were determined by X-ray diffraction (XRD), High resolution transmission electron microscope (HRTEM), Scanning electron microscope (SEM) and vibrating sample magnetometer (VSM) techniques.
