RF co-sputtered nanocomposite (Bi3Fe5O12-Bi2Dy1Fe4Ga1O12) thin films are prepared using composition adjustment approach, implemented by varying the RF powers at each sputtering target. A new MO nanocomposite material is obtained by means of applying optimized annealing crystallization process to these as-deposited garnet layers. The optimally annealed garnet nanocomposites exhibit a significant red shift of the main MO transitions and show strong Faraday rotation of about 8.8°/μm at 532 nm simultaneously with having a high MO quality and magnetization direction perpendicular to the film plane.
