Domain Wall Dynamics in Thin Magnetic Wires Under the Influence of Transversal Magnetic Field

We have studied the domain wall dynamics in thin amorphous glass-coating microwires under the influence of both axial and transversal magnetic fields. Two different regions of domain wall dynamics have been found according to the amplitude of the applied magnetic field rotated out of the wire's axis. At low amplitude, the effect of applied field rotation is reduced to the reduction of its axial component and the domain wall velocity decreases. For high amplitudes of magnetic field, the maximum velocity was found when applied field forms angle -20° with the wire's axis. The results are explained in terms of different domain wall structure, being transversal for low amplitudes of magnetic field and vortex for high amplitude of applied magnetic fields.
