Abstract

Vertically aligned magnetic anisotropic nickel (Ni) nanowire (NW) array/polydimethylsiloxane (PDMS) film was prepared from (Ni NW array)/anodic aluminum oxide by a simple matrix replacement route. The main challenge is to preserve the parallelly aligned Ni NW during replacement. The diameter and thickness of the as-prepared Ni NW and the Ni NW array/PDMS film are 8 mm and 60 μm, respectively. The magnetic property measurement shows that the film has remarkably enhanced coercivity and remanence ratio compared to that of bulk nickel and exhibits perpendicular magnetic anisotropy.
