Self-consistent energy band calculations have been made for URh/sub 3/ and UPd/sub 3/ and the fictitious compounds URh/sub 2/Pd and URhPd/sub 2/. The calculated electronic structures of these ordered compounds are used to estimate the critical concentration for the onset of ferromagnetism in the pseudobinary U(Rh/sub 1-//sub y/Pd/sub y/)/sub 3/ alloys. Calculations based on the virtual crystal approximation give results very similar to those for the ordered compounds. An explanation of the anomalous volume dependence of the alloys upon y, involving a Mott transition of the 5f electrons, is presented.
