The comparative analysis of the electrochemical deposition of Ni and Ni-Fe nanowires (NWs) into ordered porous alumina templates is presented. The method developed allows for obtaining NWs of 50 ± 5 nm in diameter and 25 μm in length, i.e., with an aspect ratio of 500. XRD data demonstrate the polycrystalline nature of Ni and Ni-Fe in a face-centered cubic close-packed lattice. Both fabricated materials, Ni and Ni-Fe, have shown ferromagnetic properties. The specific magnetization value of Ni-Fe NWs in the alumina template is higher than that of the Ni sample and bulk Ni, also the Curie temperature of the Ni-Fe sample (790 K) is higher than that of the Ni sample one or bulk Ni.
