Graphene, a two-dimensional structure made of carbon, is a material with excellent mechani-cal, electronic and optical properties. However, it did not seem suitable for magnetic applica-tions. Together with international partners, Empa researchers have now succeeded in synthesiz-ing a unique nanographene predicted in the 1970s, which conclusively demonstrates that car-bon in very specific forms has magnetic properties that could permit future spintronic applica-tions. The results have just been published in the renowned journal Nature Nanotechnology.
