Discovery of a new magnetic order
Discovery of a new magnetic order: The existence of magnetic skyrmions was already predicted over 20 years ago, but was first proven experimentally in 2009; a group of research scientists from the Technische Universität München (TUM) had identified lattices of magnetic vortices in manganese silicon in a weak magnetic field. Unlike these structures, the ones now discovered by physicists at Jülich, Kiel and Hamburg exist without an external magnetic field and are located on the surface of the materials examined, instead of inside them. Their diameter amounts to just a few atoms, making them at least one order of magnitude smaller than the skyrmions which have been identified to date.
