Key to ultra-dense next-gen data storage could be a new magnetic state found in twisted 2D materials — German researchers reveal 'super‑moiré' magnetic milestone
German researchers led by the University of Stuttgart have discovered a new magnetic state in twisted 2D materials, specifically chromium triiodide, which exhibits long-range spin textures beyond the material's moiré pattern. This finding, published in Nature Nanotechnology, showcases the potential for ultra-dense magnetic data storage. By utilizing scanning nitrogen-vacancy magnetometry, the team observed ordered magnetic textures that span multiple moiré unit cells, with implications for future spintronic concepts. While still in early research stages, this work could pave the way for advancements in magnetic data storage technologies and deepen our understanding of magnetic interactions in two-dimensional systems.
