Sažetak
We study the magnetic exchange between Mn or Cr atoms adsorbed on Ag(001) surface. By fitting DFT results on the Ising model, we show that this interaction is antiferromagnetic in both cases. We also show that when graphene is laid on top of the adatoms, the exchange interaction changes because of the bonding of graphene and the adatoms. For Cr adatoms the result of adsorption is reduction in the magnitude of the exchange parameters, but the character stays the same. For Mn adatoms bonding completely changes the exchange and opens up a possibility of a novel spin ordering.
