We studied the correlations between the structure (in particular strain) and magnetic anisotropy in thin Co/Pd(111) films uncovered and covered with Cr. Measurements were done by grazing incidence x-ray diffraction and magneto-optical Kerr effect. To properly describe these correlations, one has to consider a surface magnetoelastic coefficient. We demonstrate that Cr capping leads to an enhanced anisotropy strength due to strain effects, and an extended perpendicular anisotropy thickness range due to an interface contribution.
