      abstract     = {The current development to employ magnetic skyrmions in
                      novel spintronic device designs has led to a demand for
                      room-temperature-stable skyrmions of ever smaller size. We
                      present extensive studies on skyrmion stability in atomistic
                      magnetic systems in two- and three-dimensional geometries.
                      We show that for materials described by the same
                      micromagnetic parameters, the variation of the atomistic
                      exchange between different neighbors, the stacking order,
                      and the number of layers of the atomic lattice can
                      significantly influence the rate of the thermally activated
                      decay of a skyrmion. These factors alone are important
                      considerations, but we show that their combination can open
                      up novel avenues of materials design in the search for
                      sub-10 nm skyrmions, as their lifetime can be extended by
                      several orders of magnitude.},
