摘要：

The magnetic structure of antiferromagnetic UGa3 (T-N approximate to 64 K) has been examined by neutron diffraction measurements on a single crystal. The ordered magnetic moment is 0.74(8)mu(B) per U atom at 5 K. From measurements with an applied magnetic field we suggest that the moments are along the [111] direction. In the vicinity of 40 K the mosaic of the crystal changes significantly. This coincides with the anomaly in the magnetic susceptibility observed at the same temperature, indicating a possible crystallographic distortion or a reorientation of the magnetic moments.
