Wires with height from 9 to 26 nm, wide from 200 to 500 and length from 5 to 13 m were obtained. The atomic and magnetic force microscopy was used to study the morphology and domain structure of the obtained nanowires. Multidomain and single-domain structures depending on the width of the nanowires were observed. Current-induced phase transition from ferromagnetic to paramagnetic state in the Ni nanowires was observed when studing of current-voltage characteristics of such nanostructures. This phenomenon is explained by the Joule heating of ferromagnetic Ni nanowires by the high-density current over Curie temperature.
