Influence of aspect ratio and anisotropy distribution in ordered CoNi nanowire arrays

► Highly ordered CoNi nanowire alloys have been produced by electrodeposition. ► Electrolyte temperature ensures the deposition of CoNi alloys instead of Co and Ni segregated. ► A competition between shape and magnetocrystalline anisotropies determines the direction of the easy magnetization axis. ► Analysis of the effective anisotropy gives us information respect to the easy axis modification.
