Growth of Epitaxial Fe2O3 Films on Lithium Niobate Substrates

For the first time, epitaxial films of hematite (α-Fe2O3) and maghemite (γ-Fe2O3) were obtained on LiNbO3 substrates by the method of reactive magnetron high-frequency sputtering. The performed X-ray diffraction analysis of the obtained films showed that a small lattice mismatch allows one to obtain by this method structurally perfect epitaxial Fe2O3 layers with different polymorphic modifications on LiNbO3 substrates.
