Abstract

We have studied the low-temperature properties of Prx La1 - x Pb3 andPrx La1 - x lnAg2 with the crystal-electric-field (CEF) ground state of a non-Kramers Γ3 doublet. In Prx La1 - x Pb3, non-Fermi-liquid (NFL) behavior has been observed for Pr concentrations x≤0.05 in the specific heat C / T, susceptibility and electrical resistivity at low temperatures. Moreover, application of magnetic field raises C / T rapidly, which demonstrates the presence of the residual entropy at lower temperatures. InPrx La1 - x lnAg2, characteristic features have been seen up to x=0.8 in the susceptibility and specific heat below 15 K. These behaviors can be caused by the quadrupolar Kondo effect arising from the correlation between the dilute Γ3 moments and the conduction electrons.
