Current-induced H-shaped-skyrmion creation and their dynamics in the helical phase

Inevitable for the basic principles of skyrmion racetrack-like applications is not only their confined motion along one-dimensional channels but also controlled creation and annihilation. Helical magnets have been suggested to naturally confine skyrmions tracks formed by helices, which allow high-speed motion. We propose a protocol create topological magnetic structures in helical background. furthermore analyse stability current-driven background with in-plane uniaxial anisotropy fixing orientation helices.
