Resumen:
Specific heat anomalies due to the 7 8 thermal promotion were measured for CePd3B0.6 and CePd3Si0.3. For the heavy-fermion compound CePd3B0.6 one observes a quasi-linearC(T) dependence, instead of the expected exponential one. Moreover, the cubic crystal field splitting in theJ = 5/2 ground state alone does not explain the thermal dependence of the susceptibility. These results are discussed in terms of the different hybridization of the conduction electron states with the ground (7) and excited (8) crystal field levels. © IOP Publishing Ltd.
