  Magnetic skyrmions are nontrivial spin textures which resist external
perturbations, being promising candidates for the next generation recording
devices. Nevertheless, a major challenge in realizing skyrmion-based devices is
the stabilization of ordered arrays of these spin textures under ambient
conditions and zero applied field. Here, we demonstrate for the first time the
formation and stabilization of magnetic skyrmions on arrays of self-assembled
hexagonal nanodomes taking advantage of the intrinsic properties of its curved
geometry. Magnetic force microscopy images from the arrays of 100 nm nanodomes
showed stable skyrmions at zero field that are arranged following the
topography of the nanostructure. Micromagnetic simulations are compared to the
experiments to determine the correlation of the domain textures with the
topography of the samples. We propose a simple method to nucleate and
annihilate skyrmions, opening the possibility for ultra-dense data storage
based on the high stability and low energy consumption of the skyrmionic
textures.
