摘要：

The magnetic behaviour of single-crystalline UGa3 has been studied by means of DC-and AC-magnetic susceptibility and thermal conductivity measurements. As many as three pronounced singularities have been found in both, the chi(T) and kappa(T) variations. The features at T-N = 65 K are associated with an antiferromagnetic phase transition while those at T-1 = 40 K and T-2 = 8 K have an unknown origin. At low temperatures a significant diamagnetic response is observed in chi'(T) accompanied by a rapid rise in chi "(T). This behaviour of the AC-susceptibility is strongly dependent on the frequency of the alternating magnetic field and on the strength of the external steady magnetic field.
