Chiral Edge Currents for ac Driven Skyrmions in Confined Pinning Geometries

27 Sep 2019 Reichhardt C. Reichhardt C. J. O.

We show that ac driven skyrmion lattices in a weak pinning channel confined by regions of strong pinning exhibit edge transport carried by skipping orbits while skyrmions in the bulk of the channel undergo localized orbits with no net transport. The magnitude of the edge currents can be controlled by varying the amplitude and frequency of the ac drive or by changing the ratio of the Magnus force to the damping term... (read more)
