We present results from an ab initio study of graphene and graphene nanoribbons (GNR) doped with B7 clusters. We already showed that this system might serve as a blueprint for the controlled layout of graphene based nanodevices, where the semiconducting properties are supplemented by parts of the graphene matrix and the metallic wiring is provided by chains of boron clusters [1,2]. We study how the B7 clusters alter the physical properties of GNRs. A special focus is put on the magnetic properties of zigzag GNRs.
