In a magnetic field perpendicular to the substrate, dense and homogeneous films have been obtained. We have proposed a theoretical model that predicts the magnetic anisotropy of the crystallites, explained by the specific preferential distribution of cobalt ions in honeycomb-like lattice in LDH layers.
