Fabrication of single crystal magnetic garnet film and application to optical current transducer

This paper describes growth of single crystal magnetic garnet films by LPE, characterization of the films, and application to optical current transducer. The properties of the films investigated were thickness, surface morphology, X-ray diffraction, lattice constant, lattice mismatch between film and substrate (single crystal nonmagnetic wafer), and Faraday rotation angle. Optical CTs have been fabricated and evaluated using the films grown. The condition to obtain the films suitable for the Faraday rotators of the optical CTs was suggested.
