Fig. 7: Averaged magnetization for domain walls (DW).

Spatially averaged domain-wall dynamics along the path T(θ) from micromagnetic simulations of the 2DW state subject to a microwave current density j of 1 GHz and amplitude 10 × 10¹¹ A m⁻². The distance between the domain walls is shown to oscillate at the same frequency of the microwave current (black curve) in panel (a). The profile of the domain wall is also modified but exhibiting a more complicated pattern in panel (b). The solid and dotted lines represent each domain wall width of the 2DW state.
