Abstract
A magnetooptic garnet single crystal film for use in a Faraday rotator is Dy.sub.3-x Bi.sub.x Fe.sub.5 O.sub.12 (x=0.2-1). The garnet has a reduced temperature characteristic of the Faraday rotation angle, to thereby insure a reliable and stabilized isolation against temperature variation.
