"Co impurities on Ag and Cu: Kondo temperature dependence on substrate orientation"
P. Roura-Bas, M.A. Barral and A.M. Llois
Phys. Rev. B 79(7) (2009) 075410/1-4
The surface Kondo effect of a single Co impurity adsorbed on different noble-metal surfaces is revisited. The magnetic system mapped onto the Anderson impurity model is solved within standard noncrossing approximation techniques using data coming from electronic structure calculations. The observed experimental trends of the Kondo temperature are explained in terms of the particular features of the hybridization function and of the d impurity level position.
