  We perform systematic Langevin molecular dynamics simulations of interacting
skyrmions in thin films. The interplay between Magnus force, repulsive
skyrmion-skyrmion interaction and thermal noise yields different regimes during
non-equilibrium relaxation. In the noise-dominated regime the Magnus force
enhances the disordering effects of the thermal noise. In the
Magnus-force-dominated regime, the Magnus force cooperates with the
skyrmion-skyrmion interaction to yield a dynamic regime with slow decaying
correlations. These two regimes are characterized by different values of the
aging exponent. In general, the Magnus force accelerates the approach to the
steady state.
