Abstract
IN some optical devices the Faraday effect is used with advantage as a shutter, and, as a modulator of a light beam, it is especially useful in polarimetry1–3. In such applications a material having a large value of the Verdet constant is usually sought, consistent with adequate transmission at the desired wavelengths. While numerous materials, especially thin metal films and ferrites, are known which have large absolute values of the Verdet constant4, measurements reported here are limited to glasses.
