Uranium pnictides with the cubic Th3P4-type structure (the space group 143d) attract much attention because of a possible non-collinear magnetic structure. It is supposed1 that the magnetic structure of these crystals consists of three sublattices of U4+ ions with magnetic moments symmetrically tilted from the [111] direction at some angle. The magnetization jump has been observed2 during measurements of the magnetization along the hard direction [100] on U3As4 crystals (in a field of about 200 kOe at the temperature 4.2 K). Extensive information on its magnetic anisotropy and phase transitions induced by a magnetic field have been obtained as a result of further experimental and theoretical investigations3,4 of this substance. In U3P4, which is very similar to U3As4, the magnetization jump was not observed, however, up to 300 kOe5. The purpose of the present work consists in the investigation of U3P4 in still higher magnetic fields.
