The compounds UTAl (T = Fe,Co,Ni,Ru,Rh,Ir,Pt) crystallise in the hexagonal ZrNiAl structure. Measurements suggest that the 5f electrons in these compounds are itinerant. From self-consistent LMTO energy band calculations for the compounds, the transition to magnetism across the series is explained in terms of the calculated Stoner products. Inclusion of spin-orbit interaction leads to an induced orbital moment in URhAl, consistent with the experimental observation that the magnetic properties of these compounds are highly anisotropic.
