Abstract

The magnetic field is one of the widely used external stimuli to manipulate magnetic skyrmions. On the other hand, the skyrmion Hall effect can force the skyrmion to move perpendicular to the driving direction, which may lead to the annihilation of the skyrmion at the sample edge. Here, we study a skyrmion guide based on a nanotrack, where the skyrmion is controlled by the spin-transfer torque or spin-orbit torque in the presence of an in-plane field. The effects of spin-torque parameters, spin polarization directions, and magnetic field with an appropriate magnitude on the skyrmion motion are explored. Both static and dynamic properties of the skyrmion are demonstrated through micromagnetic simulations. Our results can be useful for the development of topological transport channels for spintronic devices.
