Abstract
A coherent picture for magnetic response of heavy fermions is provided on the basis of neutron-scattering results and the self-consistent perturbation theory. It is shown that the momentum dependence in the magnetic response is mainly due to the RKKY interaction. With growing itineracy of f electrons, another exchange interaction becomes relevant. The tiny ordered moments in some heavy-fermion systems are ascribed to dominance of the itinerant exchange.
