Cerium substituted YIG single crystalline film prepared with ultra-high-vacuum magnetron sputtering

This paper is concerned with the preparation of cerium substituted yttrium iron garnet which is known to be an oxide with a large magneto-optic effect. Using magnetron sputtering we successfully grew an epitaxial film on a nonmagnetic substrate. Here we investigate the conditions of the single crystal film growth by use of the sputtering technique: dependence of the lattice constant and the Faraday coefficient on the oxygen flow rate and the sputtering pressure. The obtained films are different from the films reported previously.
