Magnetic skyrmions are topological excitations that have attracted great attention recently for their potential applications in low power, ultrahigh density memory. A major challenge has been to find materials that meet the dual requirement of small skyrmions stable at room temperature. Here, the authors further both these goals by developing epitaxial FeGe films with excess Fe using atomic layer molecular beam epitaxy far from thermal equilibrium.
