Skyrmions are a type of topological spin texture that have generate considerable interest for use in information storage and processing, and unconventional computing. Despite this interest, controlled generation, and motion without a Skyrmion hall effect remain an issue. Here, Chen et al combine a Skyrmion hosting magnetic multilayer with a surface acoustic wave (SAW) delay line, and show how SAWs can create, order, and allow for Skyrmion motion, without the Skyrmion Hall effect.
