We present the experimental results on the in situ epitaxial growth of cerium substituted yttrium iron garnet films on three different single crystalline substrates by use of the magnetron sputtering, in particular, paying attention to the films deposited on the neodymium gallium garnet. Intrinsic properties of the grown films such as lattice constant, specific Faraday rotation, and hysteresis have been measured. We have found that the sign of the lattice mismatching between the film and the substrate is important for the enhancement of the magneto-optic effect, and the lattice matching is attainable by changing the oxygen gas flow rate while growing the crystal.
