Fluoroaluminate glasses containing various concentrations of Eu 2+ were prepared under a reducing atmosphere for the present study, and the wavelength dependence of the Faraday rotation angle was examined. The magnitude of the Verdet constant (V c ) increased as the concentration of Eu 2+ increased. In addition, the Verdet constant of glasses containing 5 cat.% Eu 2+ was larger than that of fluoroaluminate glasses containing the same concentration of Tb 3+ in the wavelength region from 400 to 600 nm. The effective transition wavelength, λ t , for glasses containing Eu 2 + as well as those containing Tb 3 + was evaluated based on the Van Vleck and Hebb theory. Factors dominating the Verdet constant of those glasses are discussed in this report.
