Thermopower Studies Of Doped Ceal2 And Ual2

We have studied the thermopower of U doped CeAl2 and Ce and La doped UAl2. Despite different ground state properties of CeAl2 and UAl2, the former being an antiferromagnetic heavy-fermion compound and the latter non-magnetic, we have found that not only thermopower data for pure CeAl2 and UAl2 are similar but also the thermopower results of doped samples behave similarly. Although the similarity seen in pure systems is yet to be understood, we interpret the doping effects as the results of changes in energy dependent relaxation time with doping.
