The paper reports the direct observation of the skyrmion Hall effect, a phenomenon where magnetic skyrmions, which are topologically charged quasi-particles, exhibit transverse motion under the influence of a current-induced spin Hall torque. The study uses a modified design of a Hall bar device with a Ta/CoFeB/TaOx trilayer to observe the motion of skyrmions at room temperature. By increasing the current density, the researchers observed a transition from creep motion to steady flow motion, revealing a significant transverse component in the skyrmion's velocity. The skyrmion Hall angle, defined as the ratio of the transverse to the longitudinal velocity, was measured to be as large as 15° at current densities below 10^7 A/cm². This finding demonstrates a strong similarity between the conventional Hall effect of electronic charges and the Hall effect due to topological charges, suggesting potential applications in skyrmionics, such as topological selection and novel functionalities. The study also highlights the role of defects in the dynamics of magnetic skyrmions, which can affect their motion and behavior near device edges.The paper reports the direct observation of the skyrmion Hall effect, a phenomenon where magnetic skyrmions, which are topologically charged quasi-particles, exhibit transverse motion under the influence of a current-induced spin Hall torque.
