Kondo properties in (Ce1-xLax)Cu5In

(Ce1-xLax)Cu5In alloys have been investigated by X-ray diffraction, specific heat, electrical transport and magnetic susceptibility measurements. Resistivity rho(T) measurements enabled the extraction of the Kondo temperature T-K(x) for the different alloys. The monotonic decrease of T-K with increase in x has been interpreted in terms of the compressible Kondo model giving \JN(E-F)\ = 0.063 +/- 0.005 (J is the strength of the on-site Kondo interaction and N(E-F) the density of states at the Fermi level). Magnetoresistivity measurements interpreted within the single-ion Bethe ansatz description corroborate the magnitude of T-K found in the rho(T) measurements.
