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 which is larger than the spin contribution to the moment. This is consistent with the experimental observation that the magnetic properties of these compounds are highly anisotropic.
