Popis:	Results of electrical resistivity, magnetization and susceptibility measurements are reported for the pseudo-ternary alloys (Ce1−xGdx)Pt2Si2. The end-members of the alloy series are the non-magnetic Kondo lattice compound CePt2Si2 and the antiferromagnet GdPt2Si2. The resistivity results reveal a rapid evolution to Kondo behaviour beyond small Ce substitution in GdPt2Si2 (for 1 − x ≥ 0.2). Coherent Kondo scattering is observed for larger Ce substitution (1 − x ≥ 0.75). The low-temperature resistivity of CePt2Si2 in the coherent state is dominantly a T2 Fermi-liquid behaviour. The magnetization results suggest metamagnetic behaviour at Gd-rich concentrations. From the susceptibility results, the Gd and Ce moments seem to contribute independently to the magnetism of the alloy samples.
