Influence of the electrodeposition potential on the crystallographic structure and effective magnetic easy axis of cobalt nanowires

Cobalt nanowires (NWs) have been synthesized by electrodeposition inside the pores of anodized aluminium oxide templates, at different values of applied deposition potential. The as-deposited NWs are parallel to one another and exhibit a high geometrical aspect ratio. The crystal structure of these...
