We present ab initio results concerning the RKKY interaction between two Co atoms placed on Cu, Au and Ag surfaces putting the main emphases on its dependence on the supporting material. Calculations based on the screened Korringa-Kohn-Rostoker (KKR) framework combined with the embedding technique are presented for FCC (100) and (110) surfaces. A test for the convergence properties with respect to the Brillouin zone integration is also shown in a selected case.
