We measure the temperature dependence of the nonlinear susceptibility Χ3, which reflects the fluctuation of quadrupolar moments, in Pr 0.05La0:95Pb3 with a Γ3 non-Kramers doublet in the crystal-electric-field ground state to provide evidence of the quadrupolar Kondo effect. Non-Fermi liquid behavior of Χ3 with a -ln T dependence is detected in the [100] and [110] directions below T ≈ 2:5 K, suggesting the screening of quadrupolar moments. In contrast, Χ3 in the [111] direction becomes constant below T ≈ 3 K. The observed features indicate that a low-lying Γ3 doublet plays a crucial role in the anomalous properties of PrxLa1-xPb3.
