    Spin-Spin Correlations of Magnetic Adatoms on Graphene
    (American Physical Society, 2015) Güçlü, Alev Devrim; Bulut, Nejat
    We study the interaction between two magnetic adatom impurities in graphene using the Anderson model. The two-impurity Anderson Hamiltonian is solved numerically by using the quantum Monte Carlo technique. We find that the interimpurity spin susceptibility is strongly enhanced at low temperatures, significantly diverging from the well-known Ruderman-Kittel-Kasuya-Yoshida result which decays as R-3.
