Magnetoelectric imprint of skyrmions in van der Waals bilayers

To effectively track and manipulate topological solitons, e.g.., skyrmions, is a key challenge before their application. Here, the authors propose a general strategy to print magnetic skyrmions to electric skyrmions in van der Waals bilayers. Through proximate interactions, there is an isoperiodic bijection between local dipoles and spin moments. This magnetoelectric imprint effect not only extends the strategies to create electric skyrmions, but also provides an approach for all-electrical readout/manipulation of magnetic skyrmions.
