Local density total energy and electronic structure calculations for NiAl, Ni3Al, FeAl and Fe3Al yield lattice constants which agree well with experiment. We find for Ni3Al the Cu3Au structure, and for Fe3Al the DO3 structure as their ground states, NiAl is paramagnetic, Fe3Al ferromagnetic, and Ni3Al and FeAl show weak itinerant magnetic phases.
