Discovery of a novel magnetic skyrmion surface state
Skyrmions get perpendicular – and push the door open for high density data storage
Skyrmion racetrack memory
Lead author Prof Shilei Zhang clarifies:
The discovery of surface pinned skyrmions has important implications for technological applications of magnetic skyrmions. First, as the surface provides an attractive potential for the skyrmions, the engineering of surfaces and interfaces allows for the precise tuning of skyrmion properties. Further, the robustness of surface skyrmions against temperature and magnetic field variations makes them ideal candidates for magnetic bits. Finally, the ability to go ‘perpendicular’ will enable new design concepts for skyrmion memory.
