Tlae effective RKKY coupling constants are derix'ed from tlae one dimensional 22-site Anderson lattice model villa various band fillings in tlte fourth order perturbationwith respect to d-f mixing element, assuming tltat the other parameters belong to tl?eKondo regime. Tlae resulting RKKY lattice naodel 1185 been exactly diagoxaalized interms of Lanczos method. The ground state /-spin correlation functions are studiedin detail. It is slaow'n that a long range corx'elation is stabilized in the case of generalfillung of conduction band compared to the nearest-neiglabor antiferromagnetieHeisenberg model, r'eflecting the colaerent nature of RKKY coupling based on tlteAnderson lattice model.Anderson lattice, RKKY lattice, spin correlation
