Abstract
Highly ordered Fe-Pt nanowire arrays were fabricated using anodic aluminum oxide templates by pulse DC electrodeposition. The influences of pulse ratio and frequency on the microstructural and magnetical properties of Fe-Pt nanowire arrays have been studied. The composition of Fe-Pt nanowires can be adjusted by pulse ratio and the crystallization of wires can be modified by pulse frequency. By choosing an optimal pulse ratio and pulse frequency, the Fe-Pt nanowire arrays with out-of plane coercivity up to 1620 Oe can be achieved. Annealing of Fe-Pt nanowire arrays could improve the crystallinity of wires and accordingly enhance the coercivity.
