Damping of the domain walls motion in Co-based amorphous ribbons with helical magnetic anisotropy: Part III

The domain structure and magnetic anisotropy in Co-based amorphous ribbons after annealing in a helical magnetic field: Part II

“…An additional pressure Dp may reach appreciable values owing to the existence of the large stray fields in a ribbon volume [9]. The change of a direction of a ribbon twisting leads to the change of a direction Dp.…”

The sandwich domain structure in a Fe-based amorphous ribbon with uniaxial magnetic anisotropy

“…The absence of the eddy currents blocking in the investigated Fe-based amorphous ribbon can be caused by the step-like character of the motion of the domain walls [7]. The last weakens the macroscopic eddy currents in the contours clasping the domain walls and therefore reduces unbalanced pressure upon them.…”

“…When approaching of the domain walls to the main opposite surfaces of an amorphous ribbon the damping coefficient, due to eddy-currents, smoothly decreases to zero [7]. The invariance of the coefficient c 1 ¼ 2m 0 M s =b at approaching of the domain walls to the main surfaces of an amorphous ribbon, indicates an increase in the damping coefficient due to diffusion and thermal magnetic after effect.…”

“…In work [7] the eddy currents blocking of the motion of the domain walls of a sandwich domain structure is revealed in a Co-based amorphous ribbon with a helical magnetic anisotropy. However, this blocking has no place in the investigated Fe-based amorphous ribbon with uniaxial magnetic anisotropy.…”

“…The dynamics of a sandwich domain structure in Co-based amorphous ribbons with a helical magnetic anisotropy was, in details, studied in works [5][6][7]. The formation of a sandwich domain structure in these ribbons is caused by strong inhomogeneity of the magnetic characteristics on a thickness of a ribbon.…”
