Propagation of a magnetic domain wall in a submicrometer magnetic wire

Abstract

The motion of a magnetic domain wail in a submicrometer magnetic wire was detected by use of the giant magnetoresistance effect. Magnetization reversal in a submicrometer magnetic wire takes place by the propagation of a magnetic domain wall, which can be treated as a 'particle.' The propagation velocity of the magnetic domain wall was determined as a function of the applied magnetic field.
