Electrodeposition of Ni nanowire arrays and their magnetic properties

In order to solve the problem that the size of the synthesized metal nanowires is single and the magnetic property is limited due to the limitation of the diameter of the anodic aluminum oxide (AAO) pore,anodic alumina (AAO) templates with different pore sizes were prepared by twice anodic oxidation...
