We report the growth of CoPtAu nanowires by electrodeposition in nanoporous anodic aluminum oxide templates. The composition analysis and elemental mapping reveals that the nanowires are composed of Co, Pt and Au, which are homogenously distributed throughout the nanowires. Under the given deposition conditions, the nanowires were dominated by Pt and Au to form a cubic PtAu phase, with the existence of the CoPt tetragonal phase at higher current densities. The nanowires obtained at 3 and 5 mA/cm2 show ferromagnetic behavior and have an easy-axis parallel to the nanowire axis.
