CoFe 2 O 4 (111) epitaxial films on a single crystalline (100) ZrO 2 (Y 2 O 3 ) substrates and non-oriented CoFe 2 O 4 films on a metal tape were grown by the metalloorganic chemical vapour deposition (MOCVD) method. The CoFe 2 O 4 /ZrO 2 (Y 2 O 3 ) films contain the coherent high-angle boundaries between variant domains due to the complex epitaxial distortions compared to polycrystalline state of the CoFe 2 O 4 /(metal tape) film. The structural peculiarities of films with variant structure lead to the strong anisotropy of its magnetooptical properties. Moreover a significant magnetorefractive effect, up to 1 % at 6 kOe, is revealed in both the polycrystalline and epitaxial films with variant structure in the near infrared spectral range.
