Abstract

The lattice parameter of cubic UxPd3S4 was measured by X-ray diffractometry for various apparent x values between 0.5 and 1.5. It seemed to change with x, but the existence of a non-stoichiometric range for uranium could not be definitely determined since the product was not in a single phase. The Rietveld refinement for UxPd3S4 (x = 1) showed that the compound was U0.90Pd3S4 and that the space group was Pm3n with the final RI value of 0.052. The lattice parameter was 6.637(1) Å, and the isotropic temperature factors were 0.59, 0.70 and 0.70 Å2 for U, Pd and S, respectively. The measured reciprocal magnetic susceptibility for U0.90Pd3S4 was not a linear function of temperature. From the slope in a temperature range of 50-200 K, the effective magnetic moment was obtained, which showed that both the U4+ and U3+ ions are present in this compound in nearly the same amounts.
