"at graphene/ heavy metal interface, strong spin-orbit coupling develops... spin canting effect stabilizes skyrmions, vortex-like spin textures, significantly mediated/ enhanced when a few ferromagnetic cobalt monolayers inserted between graphene/ heavy metal iridium, grown on insulating substrates, enhancing splitting of energy levels... spin-canting effect best with 3 monolayers... graphene-based heterostructures have great potential for the next generation of spintronic devices"
