Abstract
Dynamic property of elliptic and spiral domain structures has been studied in magnetic cylindrical microwires. The investigations have been performed using the magneto-optical Kerr-effect and the modified Sixtus-Tonks technique. The direct relation between the domain wall mobility and the domain wall length has been established for two types of domain walls. The domain wall length was controlled by the reversible change of the angle of domain wall inclination caused in turn by such type of the external parameters as axial-circular magnetic field and mechanical torsion stress.The domain wall mobility increases with domain wall length for elliptic and spiral domain walls. For the elliptic domain wall the dependence of the mobility on the domain wall length is linear.
