dc.description.abstractDynamics of topological magnetic textures are typically induced externally by, e.g. magnetic fields or spin/charge currents. Here, we demonstrate the effect of the internal-to-the-system geometryinduced motion of a domain wall in a curved nanostripe. Being driven by the gradient of the curvature of a biaxial stripe, transversal domain walls acquire remarkably high velocities of up to 100 m/s and do not exhibit any Walker-type speed limit. We pinpoint that the inhomogeneous distribution of the curvature-induced Dzyaloshinskii–Moriya interaction is a driving force for the motion of a domain wall. Although we showcase our approach on the specific Euler spiral geometry, the approach is general and can be applied to a wide class of geometries.en_US
