Abstract
Abstract The formation and structural characterization of highly (111)-oriented Co 3 O 4 and CoFe 2 O 4 films prepared by a novel procedure from 00l-oriented NaCoO 2 and Na(CoFe)O 2 is reported. The Na(CoFe)O 2 films were deposited on MgO, SrTiO 3 , LaAlO 3 , and Zr(Y)O 2 single crystals with (100) and (111) orientations by chemical solution deposition method and crystallized at 700 °C. Subsequently they were transformed into (111)-oriented spinel phase during post-growth annealing at 800–1000 °C. Morphology and structure of the films was investigated by means of scanning electron microscopy and X-ray diffraction. While all spinel films exhibit pronounced out-of-plane orientation irrespective of substrate, the rate of in-plane orientation strongly depend on lattice misfit values. Different epitaxial phenomena ranging from true one-to-one epitaxy to the existence of many-to-one epitaxy involving two or more orientations were determined by full 3D texture analysis.
