Publication number: 20070158198Abstract: Metal nanowires were formed on electroformed magnetic metals when porous templates were prepared by anodizing aluminum or its alloys. The aspect ratio of the anodic oxide pores was controlled by the electrolyte composition, electrolytic conditions, and the subsequent widen-treatment of the anodized pores. Because of the magnetic field strength of the electroformed nanowires increases with increasing the aspect ratio, the electroformed metal with higher aspect-ratio nanowires has a greater magnetic field strength. Accordingly, metals with inhomogeneous magnetic field strength were obtained.Type: ApplicationFiled: May 2, 2006Publication date: July 12, 2007Inventors: Chein-Ho Huang, Wen-Yung Shu, Chun-Yi Li, Hsiou-Jeng Shy, Hung-Fang Huang
