      abstract     = {Graphene has been identified as a promising material with
                      numerous applications, particularly in spintronics. In this
                      paper we investigate the peculiar features of spin
                      excitations of magnetic units deposited on graphene
                      nanoribbons and how they can couple through a dynamical
                      interaction mediated by spin currents. We examine in detail
                      the spin lifetimes and identify a pattern caused by
                      vanishing density of states sites in pristine ribbons with
                      armchair borders. Impurities located on these sites become
                      practically invisible to the interaction but can be made
                      accessible by a gate voltage or doping. We also demonstrate
                      that the coupling between impurities can be turned on or off
                      using this characteristic, which may be used to control the
                      transfer of information in transistorlike devices.},
