Abstract: In graphene nanoribbons of ‘zigzag’ edge orientation, the edges host unpaired electron spins that couple to generate long-range magnetic order (switching from antiferromagnetic to ferromagnetic inter-edge configuration as the ribbon width increases) under ambient conditions, enhancing the prospects for graphene-based spintronic devices.
