  The magnetic properties of the intermetallic compound FeAl are investigated
using exact exchange density functional theory. This is implemented within a
state of the art all-electron full potential method. We find that FeAl is
magnetic with a moment of 0.70 $\mu_B$, close to the LSDA result of 0.69
$\mu_B$. A comparison with the non-magnetic density of states with experimental
negative binding energy result shows a much better agreement than any previous
calculations. We attribute this to the fine details of the exchange field, in
particular its asymmetry, which is captured very well with the orbital
dependent exchange potential.
