Abstract:
The physical properties of the series CePd3Bex (0 <= x <= 0.47) have
been studied. Introducing Be into CePd3 results in a drastic reduction
of the Seebeck coefficient from 100 mu V K-1 at 300 K to -2 mu V K-1,
respectively. Paramagnetism of Ce3+ free ions and metallic conduction
dominate the physical properties. A structural transition at x = 0.25 is
accompanied by a significant lowering of the Kondo temperature and leads
to a successive suppression of the thermoelectric performance of
CePd3Bex with increasing x.
