We have been conducting a systematic investigation of the effect of chemical pressure on the ground state properties of the heavy fermion system Ce{sub 1-x}La{sub x}Al{sub 3}. We observe the development of an inelastic magnetic response below a characteristic temperature T{sup *} (2.2 K at x=0.2,2.1 K at x=0.5) from the high-temperature quasielastic response. This inelastic response is also extremely sensitive to applied pressure. Our observations are consistent with the predictions of the anisotropic Kondo model. (c) 2000 American Institute of Physics.
