Abstract

Atomic arrangement in U₂XSi₃ with X = Pt and Fe was investigated by electron diffraction and X-ray powder diffraction and discussed in conjunction with the results of magnetic susceptibility, magnetization, specific heat electrical resistivity measurements. U₂PtSi ₃ crystallizes in the simple AlB₂-type structure, where Pt and Si atoms are located at B sites disorderly and shows spin glass behavior at low temperature. Contrarily, the electron diffraction pattern for U ₂FeSi₃ reveals a superstructure doubling the lattice parameter as that observed for U₂RuSi₃, suggesting absence of the random structure. In this structurally ordered compound U ₂FeSi₃, no spin glass behavior is detected.
