Query: The effect of chemical disorder on the magnetic anisotropy of strained
  Fe-Co films   Strained Fe-Co films have recently been demonstrated to exhibit a large
magnetocrystalline anisotropy (MCA) and thus to be of potential interest as
magnetic storage material. Here, we show by means of density-functional (DF)
calculations, that chemical order can remarkably enhance the MCA. We also
investigate the effect of relaxation perpendicular to the applied strain and
evaluate the strain energy as a function of Co concentration and substrate
lattice parameter. On this basis, favourable preparation routes for films with
a large perpendicular anisotropy are suggested.
