The magnetocrystalline and magnetoelastic anisotropies of epitaxial CoO/Co(hcp) bilayers with dominating (100) crystallographic in-plane orientation have been investigated by means of light scattering from spin waves. Analysis of spin-wave frequencies measured in different sample orientations enabled distinction of several anisotropy contribution to the sample energy density. The role of a demagnetizing factor, possible out-of-plane anisotropies and their influence on the in-plane anisotropies, including the magnetoelastic contribution, were discussed.
