Reconfigurable, ordered matter offers great potential for future low-power computer memory by storing information in energetically stable configurations. An international team of researchers (UK, USA – University of Colorado) describe stable, high-degree multi-skyrmion configurations where an arbitrary number of antiskyrmions are contained within a larger skyrmion called skyrmion bags. They have demonstrated the concept experimentally and numerically in liquid crystals and numerically in micromagnetic simulations either without or with magnetostatic effects. They found the skyrmion bags to act like single skyrmions in pairwise interaction and under the influence of current in magnetic materials. The finding is an exciting proposition for topological magnetic storage and logic devices…read more. Open Access TECHNICAL ARTICLEÂ
