Abstract
In a magnetooptical element comprising a single crystal of Cd.sub.1-x-y Mn.sub.x Hg.sub.y Te, the single crystal has a composition in an area defined in a quasi three-element phase diagram of MnTe--HgTe--CdTe by four points of: Mn.sub.0.01 Hg.sub.0.04 Cd.sub.0.95 Te, Mn.sub.0.01 Hg.sub.0.1 Cd.sub.0.89 Te, Mn.sub.0.12 Hg.sub.0.17 Cd.sub.0.71 Te, and Mn.sub.0.25 Hg.sub.0.04 Cd.sub.0.71 Te. This renders the magnetooptical element suitable for use in a wavelength range between 0.8 micrometer and 1.1 micrometers.
