Lead free single crystals of the ferrimagnetic garnet Bi3-2xCa2xFe5-x-yInyVxO12 are grown by using the flux method. High quality single crystals having a dimension greater than 10 mm and few inclusions can be obtained for all materials with different In content by the technology described in this paper. Faraday rotation and optical absorption of a single crystal with x≈ 0.90, y ≈ 0.12 were measured for wavelength in the range of 0.70 to 2.2 ≈m. In spite of the remarkable increase of rotation by the bismuth substitution, no appreciable increase of absorption coefficient is observed in this wavelength region. Our results demonstrated lead free single crystals of In-BCVIG synthesized in x≈ 1.0 composition region with small amount of In substitution are a magneto-optical material with hige value of magneto-optical figure of merit. Considering its low and variable magnetization, high Curie temprature and rather large magneto-optical rotation, the above results show that the crystals can be employed in magneto-optical devices.
