Abstract

Ordered hexagonal arrays of Co(x)Ni(1-x) nanowires (NWs) with different content of cobalt (0.35 <; x <; 0.75), were successfully fabricated by a potentiostatic electrodeposition technique inside nanoporous anodic alumina templates. The CoNi NWs were electrodeposited using only one electrolyte bath and tuning the Co% by the applied deposition potential. The systematic study of the morphology, chemical composition and magnetic properties of the CoNi NW arrays was performed. The obtained results unambiguously demonstrated the influence of the Co content on the magnetic properties of CoNi NWs. The Co% was found to decrease when increasing the applied cathodic potential and the coercivity of the CoNi NWs linearly increased with the Co%.
