Abstract

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.
