Abstract:
In this work, a comparative study of the microstructure, magnetic and magnetoresistive properties of arrays of Fe–Ni nanowires with different morphologies has been carried out. They were obtained by electrolytic metal deposition in porous alumina matrices prepared by different, including original, techniques. All nanowires samples are polycrystalline and have a face-centred cubic lattice. The relationship between the remagnetisation properties and the morphology of the nanowire arrays was revealed. The presence of the magnetoresistance anisotropy effect was found, the magnitude of which was 1.3–2.3% for samples of different types.
