We use quantum Monte Carlo method to study the indirect coupling between twomagnetic impurities on the zigzag edge of graphene ribbon, with respect to thechemical potential $\mu$. We find that the spin-spin correlation between twoadatoms located on the nearest sites in the zigzag edge are drasticallysuppressed around the zero-energy. As we switch the system away fromhalf-filling, the antiferromagnetic correlation is first enhanced and thendecreased. If the two adatoms are adsorbed on the sites belonging to the samesublattice, we find similar behavior of spin-spin correlation except for acrossover from ferromagnetic to antiferromagentic correlation in the vicinityof zero-energy. We also calculated the weight of different components ofd-electron wave function and local magnet moment for various values ofparameters, and all the results are consistent with those of spin-spincorrelation between two magnetic impurities.
