• Polycrystalline La-substituted Bi : YIG films with chemical compositions of La_xBi_<0.5>Y_<2.5>Fe_4AlO_<12> (x=0,0.2,0.6,0.8,1.0,1.2) have been prepared by pyrolysis. The optical absorption coefficient, the Faraday rotation, and the apparent Kerr rotation spectra of the films were investigated in the wavelengths ranging of 400-700 nm. The optical absorption coefficient at the wavelengths ranging 450-550nm were decreased as La content increased. Both the Faraday rotation coefficient and the apparent Kerr rotation angle were enhanced by La-substitution in the wavelengths ranging 420-460 nm. As a result the magneto-optic figure of merit for the Faraday configuration as well as for the Kerr configuration was increased in the wavelengths ranging 420-460 nm. The origin of the increased figure of merit is discusse.
