摘要：

The transport, calorimetric and magnetic properties of U1-xThxBe13 have been investigated. For U0.9Th0.1Be13 we have observed all low-temperature asymptotics predicted to date for the quadrupolar Kondo effect (QKE). Namely, this compound demonstrates a logarithmic increase of C/T where C is the specific heat, square-root temperature dependences of the resistivity and susceptibility, absence of magnetoresistivity as well as deviating to positive values of the non-linear susceptibility when temperature decreases. We have found that the Hall effect for the QKE is quenched in low magnetic fields. The anomalous properties of U0.9Th0.1Be13 are compared with corresponding characteristics of UBe13 and U1-xThxBe13 for x > 0.1.
