The anodic aluminum oxide (AAO) templates were prepared by a two step anodization process in a mixture phosphoric acid, sulfuric acid and chromic acid and oxalic acid. The pore of anodic aluminum oxide templates were hexagonal arranged pore domains. Oredred Nickel nanowires were prepared in this porous anodic aluminum oxide templates from Watt solution and additives by an electrodeposition. The diameter of Nickel nanowires in the array were about 80 nm and the length is about 800 nm with the aspect ratio of about 10. The ordered Nickel nanowires were characterized by X-ray diffractometer, scanning electron microscopy and magnetometer.
