Measurements of the magnetic susceptibility (2–300 K), electrical resistivity (70 mK–300 K), specific heat (70 mK–150 K) and thermoelectric power (0.3–300 K) have been carried out on Ce x La 1- x PdSn. For all these quantities, the crystalline electric field (CEF) effect on Ce 3+ state was observed: the CEF splitting scheme does not change much for x ≥0.3. The Néel temperature decreases monotonically with decreasing Ce concentration, and the long-range antiferromagnetic order disappears for x around 0.1. The thermoelectric power of Ce x La 1- x PdSn shows complicated structures at low temperatures. These results were discussed from the viewpoint of coexistence and competition between the RKKY interaction and the Kondo effect.
