Abstract
Energy band calculations of the ground state properties of compounds in the range UM2-PuM2 (where M = Mn, Co, Fe, Ni) have been made. The Stoner criterion for the ferromagnetic instability is in good agreement with experiment for the uranium compounds, but spin-orbit coupling induces a large orbital moment in UFe2. In PuFe2 and PuCo2 the effects of spin-orbit coupling are even larger, leading to suppression of magnetism in PuCo2.
