摘要：
We calculate the dynamical susceptibility chi(ff)(q, omega) in the non-magnetic phase of the Kondo lattice using a random phase approximation at finite and zero temperature. This calculation indicates that antiferromagnetic ordering is favoured by the Kondo interactions in some regions of the model's parameters J(K), J(H) (C) 1999 Elsevier Science B.V.
