Abstract

Microscopic arguments are presented in favor of a spin nature of the heavy fermions in Kondo lattices with nearly integer valence of the f-elections. It is shown that the competition between the Kondo scattering and the indirect exchange interaction can result in stabilization of a spin-liquid state with a Fermi-type spectrum both for neutral spin and charged electron excitations. The origin of strong antiferromagnetic fluctuations is briefly discussed.
