Fermi surface manipulation informs magnetic skyrmion size, shape, and arrangement in ultra-high-density supercomputing memory

"skyrmions form primarily through DMI interaction thought to require asymmetric crystal structures, limiting usable materials... overcome: now proven skyrmions can be created in symmetric materials through different mechanism (RKKY interaction)... Lifshitz transition triggers creation... 2 nm skyrmion-based memory enables data storage density far beyond current silicon/ magnetic hard drive limits... ultra-low power, mathematically protected from heat/ physical interference, so good for long-term storage"
