Fig. 1. Micromagnetic simulations of hybrid chiral DWs for different DMI values.

(A to D) Cross-sectional view of a half simulation volume for [X(1)/Co(0.8)/Z(1)]₂₀ multilayer with D = −1.0, 0.0, 1.0, and 2.0 mJ m⁻² (top to bottom); the gray lines correspond to the Co layers. Arrows point in the direction of the magnetization, m_z is given by the color of the arrows from red (−1) to blue (+1), while m_y is displayed by the color of the grid from black (−1) to white (+1). (E to H) Polar angle θ inside the DW in each layer for D = −1.0 to 2.0 mJ m⁻². The blue-to-red gradient filling corresponds to the envelop of θ of all profiles in the different layers from bottom to top [see color scale in (E)], while the green line is θ_ave, the averaged θ of all layers across the thickness. (I to L) Azimuthal angle ψ inside the DW in each layer for D = −1.0 to 2.0 mJ m⁻². The blue-to-red lines again correspond to the layers from bottom to top.
