Abstract

Specific heat, susceptibility and high-field magnetisation experiments have been performed on a number of pseudobinary U(Pt1-xPdx)3 compounds with x≤0.30. For low Pd concentrations (x≤0.10) the spin-fluctuation contribution to the specific heat is enhanced with respect to pure UPt3. For x≥0.15 the spin-fluctuation phenomena are lost. On alloying, the anomalies present for UPt3 in the susceptibility at 17 K and in the high-field magnetisation at 21 T (at 4.2 K), shift towards lower temperatures and fields, respectively, and have not been observed in a compound with x=0.15. Superconductivity has not been found down to 40 mK in a U(Pt0.995Pd0.005)3 sample.
