Fine-tuning of magnetic states via an understanding of spin injection on the edge of graphene nanoribbons should allow for greater flexibility of the design of graphene-based spintronics. On the basis of calculations, we predict that coupling constants of the exchange interaction in the series of nitroxide-functionalized ribbon compounds are antiferromagnetic across the ribbons with values 0.2-0.4cm(-1) and ferromagnetic along the ribbon with absolute values from 0.05 to 0.07cm(-1). Such interacting nitroxide groups induce spin polarization of the edge states of stable graphene nanoribbons.
