Magnetic skyrmions are fascinating spin structures from a physics perspective due to their topological stabilization but are also considered for next-generation non-conventional computing devices [1,2]. Skyrmions must be hosted in a finite-sized sample for a device application, and the dynamics can differ from those in continuous film geometries. We investigate the dynamics of a driven confined skyrmion ensemble and find different meta-stable states to occur [3].
