Title: Plastic flow and the skyrmion Hall effect

Abstract

Skyrmions in chiral magnets are a particle-like texture that has been attracting growing interest due to their novel dynamics and possible applications. Here, we discuss the role of disorder and skyrmion-skyrmion interaction in governing their motion under an external drive.

Fig. 1 Fig. 1: Illustration of the motion of skyrmions with different sizes in the presence of disorder. Schematic of the experiments by Zeissler et al, who use imaging to examine moving skyrmions with different diameters. The skyrmions move at an angle with respect to the drive known as the skyrmion Hallmore » angle. a The results expected if the skyrmion Hall angle depends on the size of the skyrmions, with different size skyrmions moving at different angles. This can occur if the background potential is weak. b The observed results in which the skyrmion Hall angle is independent of skyrmion diameter. The skyrmions undergo plastic motion due to strong interaction with the pinning sites, implying a strong underlying disordered background.« less
