The unique magnetic structure and property of intermetallic uranium compounds UGa3 have been investigated by neutron diffraction measurements. With applying pressure we succeeded in revealing the magnetic structure of UGa3. We suppose that the magnetic moment of UGa3 at low pressures is along the <011> direction and that at 2.2 GPa along the <111> direction. The Néel temperature and magnetic moment are reduced with applied pressure.
