Information regarding the atomic structure in very strong magnetic fields is important in studies of neutron stars. The present paper reports the results of variational Hartree-Fock (HF) calculations for matter in strong magnetic fields. It is pointed out that these calculations are the first self-consistent studies in which exchange is properly treated for atoms heavier than helium in high fields. For this reason, the calculations are particularly important for neutron star surfaces, where the dominant material is believed to be iron. In the case of helium, it is found that molecular chains are energetically favored over isolated atoms, in agreement with previous studies. On the other hand, for iron no binding of the solid is found.
