Abstract: Highly ordered ternary alloy nanowire arrays have been fabricated within nanochannels of anodic alumina membrane by electrochemical deposition. Scanning electron microscopy and transmission electron microscopy observations show that the nanowires are smooth, uniform and straight. The XRD gives the microstructure information on samples annealed at different temperatures under Ar atmosphere. Magnetic measurement shows that the nanowire arrays have higher coercivity than that of the thin magnetic film with similar composition. Meanwhile, the relation between the coercivity and annealing temperature has been studied.

Key words: Alumina template, Nanowire array, Coercivity
