Dataset associated with "Diameter-independent skyrmion Hall angle observed in chiral magnetic multilayers"

Magnetic skyrmions are topologically non-trivial nanoscale objects. Their topology, which originates in their chiral domain wall winding, governs their unique response to a motion-inducing force. When subjected to an electrical current, the chiral winding of the spin texture leads to a deflection of the skyrmion trajectory, characterized by an angle with respect to the applied force direction. This skyrmion Hall angle was believed to be skyrmion diameter-dependent. In contrast, our experimental study finds that the skyrmion Hall angle is diameter-independent for skyrmions with diameters ranging from 35 to 825nm. At an average velocity of 6 ± 1 m/s, the average skyrmion Hall angle was measured to be 9° ± 2°. In fact the skyrmion dynamics is dominated by the local energy landscape such as materials defects and the local magnetic configuration
