Magnetizing mechanism of the amorphous ribbons with the helical magnetic anisotropy

A helical magnetic anisotropy in amorphous Co sub 68 Fe sub 4 Cr sub 4 Si sub 13 B sub 11 ribbon has been induced by annealing in helical magnetic field. The ribbon magnetizing with the help of large Barkhausen jump in the 'sandwich structure' model is realised by the appearing two domain...

Description
Summary:A helical magnetic anisotropy in amorphous Co sub 68 Fe sub 4 Cr sub 4 Si sub 13 B sub 11 ribbon has been induced by annealing in helical magnetic field. The ribbon magnetizing with the help of large Barkhausen jump in the 'sandwich structure' model is realised by the appearing two domain walls near the middle of the ribbon and their next movement to the opposite ribbon surfaces. The domain wall velocity near the middle of the ribbon is higher by an order of magnitude than near the ribbon surface.
