✦ Synopsis

Highly ordered Co nanowire arrays were grown using a direct current (DC) electrodeposition method based on an anodic aluminum oxide (AAO) template. The electrolyte consists of CoSO 4 Á 7H 2 O and H 3 BO 3 in distilled water. Co nanowires fabricated by electrodeposition are cylindrical monocrystals with a packed surface, and behave as hcp dominant structures. The nanowires are preferentially oriented along the [1 0 0] direction. The effective demagnetizing factors parallel and perpendicular to the plane of the film are N eff(J) ¼ 0.65 and N eff(?) ¼0.175, respectively. The magnetic property of the Co nanowire arrays depends on the concentration of the deposition electrolyte and the deposition voltage.
