Abstract

Bi₃Fe₅O₁₂ thin films have been deposited onto single crystal Gd₃Ga₅O₁₂O (111) substrates by the technique of pulsed laser deposition. X-ray diffraction patterns and cross section transmission electron micrographs show epitaxial growth and a flat interface between film and substrate. The magnetic-optic Faraday rotation is high, with a peak value of 22deg/μm at 560nm. The films have been used to visualize at low temperature the out of plane flux density distribution at the surface of a patterned high Tc superconducting thin film
