Skyrmion relaxation dynamics in the presence of quenched disorder
(American Physical Society, 2019-07-09)
Using Langevin molecular dynamics simulations we study relaxation processes of interacting skyrmion systems with and without quenched disorder. Using the typical diffusion length as the time-dependent length characterizing ...
Reversible to irreversible transitions in periodically driven skyrmion systems
(Institute of Physics Publishing, 2019-01-08)
We examine skyrmions driven periodically over random quenched disorder and show that there is a transition from reversible motion to a state in which the skyrmion trajectories are chaotic or irreversible. We find that the ...
Effect of the Magnus force on skyrmion relaxation dynamics
(Amer Physical Soc, 2018-01-10)
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 ...
