Abstract :
The 3 inch in diameter (TmBi)3(FeGa)5O12 epitaxial films with thickness up to 60 μm were grown by liquid phase epitaxy method. The Bi2O3, Bi2O3-B2O3, Bi2O3-B2O3-Na2O and Bi2O3-B2O3-CeO2 fluxes were used. The conditions of orthoferrite and garnet primary phase crystallization and optimal growth strategy were determined. It was found that the surface morphology strongly depends from film-substrate lattice mismatch. All films with mirror surface demonstrate high Faraday rotation and low saturation magnetization which are suitable for magneto-optic applications.
