Abstract

Heat capacity experiments, crystal structure determination and transmission electron microscopy have been carried out on U₃Cu₃Sn₄ singlecrystals. U₃Cu₃Sn₄ was confirmed to be a heavy-fermion antiferromagnet (T_N = 13(1)K) with a low-temperature electronic heat capacity coefficient γ = 390 mJ/mol_UK². Low-temperature heat capacity experiments on a U₃Ni₃Sn₄ single-crystal indicate that below 0.4 K there is a crossover between the previously observed non-Fermi-liquid behavior and a Fermi-liquid state.
