Although single crystals of hexaferrites have received considerable attention, the same does not apply for thin films. Here, the growth of epitaxial thin films of Sr2Co2Fe28O46 on a SrTiO3(111) by a chemical solution deposition method is reported. Using X-ray diffraction analysis, the orientation relationship between film and substrate was established as (000l)X || (111)STO and 112̅0X || 101̅STO. The magnetization and magnetic domain structure were investigated using magnetic measurements and Lorentz transmission electron microscopy, respectively. With changing temperature, the magnitude of magnetization in the (0001) plane changed at ∼355 K, while that along the [0001] direction remained almost unchanged, suggesting a spin reorientation transition. Using the ferromagnetic resonance method, it was shown that the compound exhibits a change in the orientation of the magnetic anisotropy in the (0001) plane at ∼ 150 K that supports the occurrence of the multiaxial anisotropy state in film similar to that in single crystals.
