(a) Schematic diagram of the magnetic multilayer consisting of a vortex-type free layer and a uniformly-magnetised reference layer. (b) Time evolution of the normalised centre position of the vortex core in the presence of a direct current. The inset shows a limit-cycle oscillation of the vortex core in a steady state.
