Fig. 5: Current-driven dynamics of AFM bimeron clusters.

a The steady motion speeds of the AFM bimeron clusters excited by CIP and COP. The results are obtained using both micromagnetic simulations and the semianalytical approach described by Eq. (4), with j = 1 × 1010 A m−2 and P = 0.1. b The corresponding effective spin torque forces.
