• Magnetic Susceptibilites of cubic UO_<2+x> (x=0.00_3-0.24_8) were measured over the temperature range between 77°K and 1100°K. Susceptibilities of UO_2 single crystals follow the Curie-Weiss law with a high value of the Weiss constant (-22_0°K). The phase boundaries between one phase (UO_<2+x>) and two phases (UO_<2+x> and U_4O_<9-y>) in helium atmosphere were obtained from the breaks in the inverse susceptibility-temperature relations of the intermediate oxides from UO_2 up to U_4O_9. The susceptibility data of UO_2 and U_4O_9 were discussed in terms of the ground state configuration f^2 perturbed by the crystalline field, in connection with the results of neutron diffraction.
