Magnetic bimerons as skyrmion analogues in in-plane magnets
A magnetic bimeron is a pair of two merons and can be understood as the in-plane
magnetized version of a skyrmion. Here we theoretically predict the existence of single …

Skyrmion ratchet propagation: utilizing the skyrmion Hall effect in AC racetrack storage devices
Magnetic skyrmions are whirl-like nano-objects with topological protection. When driven by
direct currents, skyrmions move but experience a transverse deflection. This so-called …
