Abstract
Dynamics of the domain wall between circular magnetic domains in amorphous ferromagnetic Co68.2Fe4.3Si12.5B15 wire was studied in a small region around the domain wall equilibrium position in an inhomogeneous magnetic field. The wire was prepared using the in-rotating-water-quenching technique. Small helical anisotropy was induced in the wire by current annealing and simultaneous application of tensile stress and torsion. The inhomogeneous magnetic field acted on domain wall by restoring force directly proportional to the displacement of the domain wall from its equilibrium position. Domain wall position was monitored by circular magnetic flux measurements from which it results that domain wall motion can be modeled by the motion of a very strongly damped pendulum. The value of domain wall mobility obtained from these experiments is in good agreement with the values calculated and measured for domain wall driven by a constant magnetic field.
