Abstract
Ni nanowires were deposited into nanoporous alumina by pulse electrodeposition. The temperature dependent magnetic properties are analyzed in detail and a maximum of coercivity and anisotropy field is observed around room temperature which cannot simply be explained by shape anisotropy. A model is proposed which considers the competing magnetoelastic anisotropy originating from the difference in thermal expansion coefficient of the Al-substrate and the filled alumina template.
