Abstract
The temperature-composition (T-x) phase diagram and NFL characteristics in the electrical resistivity rho(T), specific heat C(T), and magnetic suscept ibility chi(T) at low temperatures for the systems U1-xMxPd2Al3 (M = Y,Th) are described. The T-x phase diagram, the NFL characteristics, and the unde rlying mechanism for the NFL behavior are distinctly different for hi = Y-3 + and Th4+, apparently reflecting the difference in Valence of the M atom substituents, and suggesting that U is tetravalent in these two systems.
