Abstract
The thermoelectric power S(T) of single crystals of the antiferromagnetically ordered heavy-fermion superconductor UPd2AI3 (T(N)=14K, T(c)=2K) as well as of polycrystalline UNi2Al3 (T(N)=4.6K, T(c)=1K), UPd2Al3 and of the ternary heavy-fermion system UCU4+xAlg-x has been measured in the temperature range 2K less-than-or-equal-to T less-than-or-equal-to 350K. A temperature dependence of the thermopower, S(T)=A-T/(1+T/T'), was found at sufficiently high temperatures for all of these systems and for the well known heavy-fermion compounds UBe13 and UPt3.
