ABSTRACT:
According to this invention, a magnetooptical element represented by (Cd.sub.1-X-Y Mn.sub.X Hg.sub.Y).sub.1 Te.sub.1 (0<X<1, 0<Y<1) comprises, so as to be used in a range around each of wavelength bands of 0.98 .mu.m, 1.017 .mu.m, 1.047 .mu.m, and 1.064 .mu.m, a single crystal having a composition contained in an area defined in a quasi ternary-element phase diagram of MnTe-HgTe-CdTe by four points a, b, c, and d of:
