a–c Spin-transfer-torque drives the skyrmion (a), antiskyrmion (b), and high-Q skyrmionic structure (c) to move along the DMI-engineered racetrack. The dotted line marks the initial position of the magnetic skyrmionic structures. d Various skyrmionic structures’ velocity v as a function of electrical current density j. The empty symbols mean that the skyrmionic structures will annihilate at the present current density.
