Synthesis and magnetic properties of multifunctional CoPtAu nanoparticles

The synthesis and magnetic properties of multifunctional CoPtAu alloy nanoparticles of three compositions by a modified polyol process are described. The x-ray diffraction and transmission electron microscopy analyses have shown the formation of the alloy nanostructure comprising Au-rich and Pt-rich nanophases, with a narrow distribution of particle sizes and have provided the structural arrangements.
