Abstract

We have studied four compounds, ThPd₂Sn, UPd₂Sn, NpPd₂Sn and PuPd₂Sn, crystallizing with an orthorhombic crystal structure within the Pnma space group. While UPd₂Sn is a paramagnet, the ternaries NpPd₂Sn and PuPd₂Sn order antiferromagnetically at T_N = 15 and 11 K, respectively. All three compounds exhibit features characteristic of systems with strong electronic correlations, like large negative paramagnetic Curie temperatures, negative logarithmic slopes of the magnetic contribution to the resistivity and strongly enhanced low-temperature electronic specific heat. It seems probable that NpPd₂Sn and PuPd₂Sn are rare representatives of heavy-fermion systems amidst Np- and Pu-based intermetallics.
