From: Skyrmion-skyrmion and skyrmion-edge repulsions in skyrmion-based racetrack memory
Effect of different (a) applied fields and (b) perpendicular magnetic anisotropies (PMA) on the equilibrium spacing de between consecutive skyrmions and equilibrium skyrmion size rs on 40-nm-wide racetrack.
The inset shows the definition of the size of a skyrmion as the diameter of a circle at which mz = 0. Symbols are numerical results and dashed lines are used to guide the eyes.
