dc.description	In this work, we investigated the motion of a skyrmion on an asymmetric disk induced by an out-of-plane spin-polarized current. The appearance of two movement regimes based on disk asymmetry was reported. A tangential component is induced in the restoration force by the asymmetry, which in turn competes with the tangential component of the STT force. For a disk with low asymmetry, a precession motion was obtained and for a disk with high asymmetry, a convergent movement to points of stagnation was reported. These regimes can be understood as a result of competition between restoration forces and STT forces. © 2020 Elsevier B.V.
