Abstract

We investigated the current-induced dynamics of magnetic skyrmions in Pt/Co/Ir trilayers thin films. Skyrmions segregate in the transverse direction to the current flow via the skyrmion Hall effect, which shows scalability for current density and wire width. We also found the non-local accumulation of nonequilibrium skyrmions under charge current, which has an analogy with the spin accumulation in the nonlocal configuration.
