- Аннотация: A method for observation of domain walls motion in glass-coated Co-based amorphous micro-wires is proposed. Using the method, the magnetization reversal of the micro-wire induced by current pulses of high amplitude is studied. It is shown that the magnetization reversal occurs due to the nucleation of the domain walls at the sample ends and their subsequent motion along the micro-wire. The dependencies of the domain wall velocity on the current pulse amplitude and an external longitudinal DC magnetic field are measured. A simple model describing main features of experimental data is presented.
