| Description |
The single ferromagnetic Ni nanowires connecting two contact pads on the silicon oxide surface were fabricated using the scanning probe nanolithography technique based on the nanoindentation of polymethylmethacrylate resist and lift-off process. 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. |
