Exploring RF Magnetron Sputtering Growth Composite Thin Film BiFeO-BiFeO on C-Plane AlO Substrate.

Nanocomposite films of BiFeO-BiFeO were fabricated on a sapphire substrate AlO using the method of gas discharge high-frequency cathodic sputtering of a ceramic target with a stoichiometric composition in an oxygen atmosphere. The results of the film analysis using X-ray structural analysis, Raman scattering, XPS, and atomic force microscopy are presented. The lattice parameters, surface topography, chemical composition of the films, concentration, and average sizes of the crystallites for each phase were determined.
