Twisted 2D Crystals Produce Giant Magnetic Skyrmions
Edinburgh researchers created stable magnetic skyrmions stretching 300 nanometers by twisting atomically thin chromium triiodide layers, opening a path to low-power spintronic devices.
Key Takeaways
- Skyrmions stretched to 300nm, far beyond expected moire pattern scale
- Optimal formation at 1.1 degree twist angle in chromium triiodide bilayers
- Could enable low-power spintronic devices without lithography or external fields
