We present the thermoelectric power S(T ) of the Ce(Pd 1−x Cu x ) 2 Si 2 alloy for temperatures 1.5 K < T < 300 K. We observe three characteristic features across the 0 < x < 1 substitution range: two positive maxima and a negative minimum, that are typical for Ce compounds that display, or lie close to, magnetism. Our analysis of the data shows that the high-T maximum is related to the Kondo effect on excited crystal-field levels, but that the low-T one cannot be simply associated with the Kondo scale, T K . We speculate that disorder induced by alloying can be at the origin of this discrepancy and can also be responsible for the low S(T ) measured at low temperatures in the 0.2 < x < 0.8 concentration range. We have extended electrical resistivity measurements on Ce(PdCu)Si 2 (x = 0.5) down to T ∼ 40 mK in applied fields as high as 16 T.
