摘要：

Ternary uranium compounds UCu2Sn and UAu2Al have been found to crystallize in the hexagonal ZrPt2Al- and orthorhombic YPd2Si-type structures, respectively. Magnetic-susceptibility, electric-resistivity and specific-heat measurements reveal that UCu2Sn, UPt2Sn and UAu2Al undergo antiferromagnetic transitions at 16.6, 60 and 25 K, respectively. With decreasing temperature below T(N), the resistivity of UCu2Sn exhibits a pronounced peak, whereas those of the other two show a precipitous drop. The extrapolated value of C/T at 0 K ranges from 17 mJ/K2 mol for UPt2Sn to 102 mJ/K2 mol for UAu2Al.
