Merons, topological structures based on in-plane magnetized magnetic materials, could have numerous valuable applications, particularly for carrying information or storing magnetic charge. Most past realizations of these structures, however, were limited in size and thermal stability or had impractical requirements, such as the application of external magnetic fields.
