Graphene nanoribbons, which are narrow strips of nanoscale honeycomb carbon structures, exhibit remarkable magnetic properties due to the behaviour of unpaired electrons in the atoms' π-orbitals.

Pattern template for graphene nanoribbons: Depending on the direction of the ribbon axis, graphene nanoribbons have an armchair edge (orange) or a zigzag edge (blue). (Image: Empa) Graphene ...
