(a) Schematic of a cylindrical nanodot and image of the simulated Néel skyrmion magnetization configuration in Permalloy cylindrical nanodot with R = 40 nm and h = 27 nm. The magnetization is colored according to the value of the mz component, as indicated previously. (b) State diagram for the Néel skyrmion configuration. Theoretically predicted region is delimited by black curves, while the simulated region—by the green curves. (c) The total energy of the Néel skyrmion and vortex state as a function of the dot aspect ratio as predicted by the analytical model.
