Magnetic nanowires made of permalloy can be ideal materials for their production. The presented experimental and theoretical investigations of the FeNi nanowire matrix are the first stage of studies aimed at designing artificial neural networks. FeNi nanowires with a diameter of 40 nm were synthesized in alumina membranes by electrodeposition at potentials ranging from -1.0 V to -1.3 V vs. Ag/AgCl. Increasing voltage caused changes in the chemical composition of nanowires with a gradual increase in Ni content. Nanowires obtained at lower potentials showed an anomalous character of co-deposition. The elemental content influenced the phase composition.
