We have investigated the optical absorption and magneto-optical properties of quaternary Cd1-x-y Mnx Coy Te crystals (x=0.37; 0y0.009) grown by the vertical Bridgman method. The presence of Co showed a significant enhancement of magneto-optical effects as compared to ternary Cd0.63 Mn0.37 Te system with the same Mn content. Four features were observed in magnetic circular dichroism (MCD) spectra of these alloys; located near 1.37; 1.45; 1.82; and 2.13 eV. We present detailed temperature dependences of the position and intensity of these MCD features; and we discuss their possible origins. © 2009 American Institute of Physics;
