Resumen:
Fitting ab initio total energies, obtained within the generalized gradient approximation with spin-orbitcoupling and a correction that includes Coulomb repulsion, we calculate the anisotropy parameters D and E ofan effective spin model that describes 3d magnetic impurities separated from the Cu͑100͒ surface by a mono-layer of Cu2N. Assuming a general exchange interaction between conduction and 3d electrons we construct aneffective Kondo model which depends on D and E. We discuss the specific cases for Mn, Fe, and Coimpurities.
