Abstract
By combining the results of muon spin relaxation and inelastic neutron scattering in the heavy fermion compounds (), we show that static magnetic correlations are suppressed above a characteristic temperature, , by electronic dissipation rather than by thermal disorder. Below , an energy gap opens in the single-ion magnetic response in agreement with the predictions of the anisotropic Kondo model. Scaling arguments suggest that similar behavior may underlie the “hidden order” in .
