Abstract

The magnetooptical Faraday rotation (θ_F) spectra of highly bismuth-substituted yttrium iron garnet (R_3-xBi_x Fe₅O₁₂, 0⩽x ⩽2.0) films prepared by the sol-gel method were studied in the photon energy ranging from 1.5 eV to 3.4 eV. It is shown that the enhancement of θ_F by high bismuth substitution can be explained by adding the contributions of the paramagnetic-type transitions to those of the diamagnetic-type transitions in the foregoing theory based on the charge transfer transition
