LOW-TEMPERATURE SPECIFIC-HEAT AND THERMAL-CONDUCTIVITY OF ANTIFERROMAGNETIC KONDO ALLOY CEPDGA

We have measured the specific heat and thermal conductivity of the pol ycrystalline Kondo alloy CePdGa. The specific heat shows high a Sommer field coefficient, an antiferromagnetic transition at T-N = 1.8K and a n anomalous residual term around T-m = 1.2K. The thermal conductivity data fit accuratly to a kappa = aT expression at very low temperature and the magnetic contribution to 1/kappa follows a theoretically predi cted In(T) dependence.
