Dynamics of hybrid magnetic skyrmion driven by spin–orbit torque in ferrimagnets

Magnetic skyrmions are magnetic textures with topological protection, which expected to be information carriers in future spintronic devices. In this work, we propose a scheme implement hybrid (HMS) ferrimagnets, and study theoretically numerically the dynamics of HMS driven by spin-orbit torque. It is revealed that skyrmion Hall effect depends on helicity net angular momentum ({\delta}s), allowing effective modulation motion through tuning Dzyaloshinskii-Moriya interaction {\delta}s. Thus, can suppressed selecting suitable materials better control motion. Moreover, Magnus force for finite {\delta}s suppresses transverse enhances longitudinal propagation, resulting ferrimagnets faster than antiferromagnets.
