"Uncovering High-Order Skyrmions and Antiskyrmions"

Researchers have discovered co-existing magnetic skyrmions and antiskyrmions of arbitrary topological charge at room temperature in magnetic Co/Ni multilayer thin films, opening up new possibilities for skyrmionics research. These spin objects, resembling tornado-like whirls in magnetic materials, offer potential applications in information storage devices and unconventional computing. The study, published in Nature Physics, also demonstrates the efficient control of the motion of these spin objects, providing insights for the development of skyrmionic devices.
