We have studied the low-temperature properties of Pr(Pb 1-xSnx)3 for a wide range of Sn concentration by measuring specific heat and susceptibility. In PrPb3 a sharp peak is observed at TQ = 0.4 K in the specific heat, which is due to a quadrupolar ordering. For x = 0.03, the peak is suppressed below 0.1 K, while the peak shifts to higher temperatures with further increase of Sn concentration. For x = 0.2, the peak is observed at ∼0.2 K. The possible origin of this behavior will be discussed.
