Ab initio electronic-structure calculations for the normal metallic st
ate of U(2)T(2)X (T = Co, Ni, Rh, Pd, Ir, Pt; X = In, Sn) compounds we
re performed using a fully relativistic optimized LCAO method based on
the local density approximation. The particular electronic structure
and related properties originate from the interplay between the band f
illing of T atom d-states and hybridization between T atom d-states an
d U atom f-states.
