Kondo behavior of anisotropic single atomic spins on a Cu2 N molecular layer

Fitting ab initio total energies, obtained within the generalized gradient approximation with spin-orbit coupling and a correction that includes Coulomb repulsion, we calculate the anisotropy parameters D and E of an effective spin model that describes 3d magnetic impurities separated from the Cu(10...
