“…The AAO membranes were fabricated by a two-step anodization process of high-purity (> 99.997%) aluminum foils [1], in 0.3 M oxalic acid at 40 V and 5 • C. The first and second anodization processes were performed for 24 and 48 h, respectively, in order to obtain AAO membranes with ordered hexagonal arrays of pores and membrane thicknesses of ∼ 70 µm. Additional details on the membranes preparation can be found elsewhere [21,22,23]. For the further potentiostatic electrodeposition process inside the AAO nanopores, the Al substrate was removed by chemical etching in a 0.2 M CuCl 2 and 4.1 M HCl aqueous solution at room temperature.…”

Highly ordered Co x Ni 1−x nanowire (NW) arrays were electrodeposited inside nanoporous anodic aluminum oxide membranes. The control of the applied potential during the electrodeposition process allowed us to easily tune the Co% in the alloy. Systematic studies on the morphological and crystallographic properties together with static and dynamic magnetic characterizations were performed. In this work we focus on the study of the dynamic magnetic properties of CoNi NW arrays using the ferromagnetic resonance method at both room (RT) and low (LT) temperatures. The careful comparison analysis performed between the magnetic anisotropy fields obtained at RT and LT, allowed us to extract for the first time the magnetocrystalline anisotropy effect of the Co component and, most importantly, the magnetoelastic anisotropy effect of Ni.

“…To determine the compositional ratio of Co and Ni in the NW arrays, energy dispersive X-ray spectroscopy (EDS) has been used. The obtained spectra allowed us to quantify the Co% of the NW arrays (Table 1) and determine its dependence on the electrodeposition potential E [11,22,26].…”
