Spiral structure with DM-induced distortions. Schematic illustration of tilt distortion expected due to the transverse DM interaction \(\varvec{D}_1^{ac}\) (Fig. 2c). The cones represent canted spiraling magnetic moments with incommensurate propagation along the leg direction and \(\varvec{\kappa }_\text {NN}\) denotes the vector chirality on the nearest-neighbor leg bonds. Opaque (transparent) colors are used to depict the situation with (without) DM interactions.
