In non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya (DM) exchange stabilizes tubular baby-Skyrmions, i.e. smooth, topological, and static spin textures. Chiral Skyrmionic state may exist in many magnetic systems due to the DM-couplings as leading spin-orbit effect, if allowed by crystal symmetry or induced by broken inversion symmetry at surfaces.
