|a CeAl₂ has attracted considerable attention because of its unusual properties including a proposed competition between Kondo and anti=ferromagnetic spin-density wave ordering observed at low temperatures. Here we present results of a self-consistent spin-polarized linear muffin tin orbital band study of CeAl₂. In its paramagnetic state the Ce-f band is about 1 eV wide and, although principally above E/sub F/, it accommodates the additional 4f electron when compared to LaAl₂ and gives rise to a very high DOS at E/sub F/. The ferromagnetic state is found not to be stable. By contrast, the anti-ferromagnetic state is found to be stable with a magnetic moment of 0.88..mu../sub B/ per Ce atom in very good agreement with neutron measurements by Barbara et al. Surprisingly, the anti-ferromagnetic spin-density ordering appears to be related to nesting features in the underlying Fermi surface in LaAl₂ (i.e., no 4f electron) rather than that of CeAl₂
