Abstract
Temperature-composition (T-x) phase diagrams and non-Fermi liquid (NFL) cha racteristics in the electrical resistivity, specific heat, and magnetic sus ceptibility at low temperatures for the U1-xMxPd2Al3 (M = Y,Th) systems are described. The T-l phase diagrams, the NFL characteristics, and the underl ying mechanisms for the NFL behavior exhibit distinct differences for M = 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.
