Title: Magnetic correlations and the anisotropic kondo effect in Ce{sub 1-x}La{sub x}Al{sub 3}.

Journal Article · · Phys. Rev. Lett.

By combining the results of muon spin relaxation and inelastic neutron scattering in the heavy fermion compounds Ce{sub 1-x}La{sub x}Al{sub 3} (0.0 {le} x {le} 0.2), we show that static magnetic correlations are suppressed above a characteristic temperature, T*, by electronic dissipation rather than by thermal disorder. Below T*, 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 URu{sub 2}Si{sub 2}.
