ELECTRICAL-RESISTIVITY, HEAT-CAPACITY AND MAGNETIC-SUSCEPTIBILITY ANOMALIES IN CE1-XLAXIR2GE2

The results of electrical resistivity rho (1.4-300 K), heat capacity C and magnetic susceptibility chi measurements on the alloys, Ce1-xLaxI r2Ge2, are reported. The results establish that CeIr2Ge2 is one of the rare Ce compounds with a Kondo coherence temperature as large as 80 K in the trivalent limit of Ce. Apparently, rho exhibits non-Fermi liqu id behaviour in the low-temperature rho data, though there is no corre sponding anomaly in the C data. There is a low-temperature tail in chi which appears to be intrinsic.
