Abstract

The magnetooptical Faraday rotations of epitaxial films of Bi₃Fe₅O₁₂ (Bi:YIG) grown on [111]-oriented gadolinium gallium garnet (GGG) substrates by pulsed laser deposition (PLD) were studied with bismuth content x = 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. The Faraday rotation angles, θ_F, of the films were measured by the method of rotating analyzer ellipsometry (RAE) with the photon energy varied from 1.5 to 3.5 eV. It was shown that in addition to the increase of. the Faraday rotation with increasing x, the peaks of θ_F shifted toward the red region as x changed from 1.0 to 1.5. The peak positions of θ_F for the completely Bi-substituted iron garnet, Bi₃Fe₅O₁₂ (BIG), were found at 2.4 and 2.8 eV with peak values as large as -23deg/μm and 44 deg/μm, respectively.
