Essay

The work is devoted to investigation of forming and dynamics of the sandwich domain structure in an amorphous ribbon (Co68Fe4Cr4Si13B11) with induced helical magnetic anisotropy. Methods of domain wall coordinate determining in the sandwich domain structure as well as determining of damping coefficient and stray field dependence on domain wall coordinate on the basis of EMF instantaneous value measuring of induction coil and field coil, and EMF Matteucci have been developed. It has been shown that experimental results of the ribbon remagnetization study (f = 1.5-5 kHz) can be good explained by the model of the sandwich domain structure. The model of magnetization inversion in domains of the sandwich domain structure under the action of stray fields that results in reversal of the domain wall macroscopic motion in the ribbon with the helical magnetic anisotropy has been developed
