FIG. 1.

MCD spectra taken at at various magnetic fields from to 5 T for the sample. The inset shows normalized intensities of MCD peaks A and B. Peak B is magnified 20 times for clarity.

FIG. 2.

Upper panel: MCD spectra taken at at magnetic field of for three CdMnCrTe samples with Cr concentrations from 0% to 3%. Lower panel: absorption spectra of the same CdMnCrTe samples measured at zero field and 2 K. The shoulderlike feature seen in the vicinity of 1.66 eV occurs at the same energy position as the MCD peak B.

FIG. 3.

Field dependence of MCD signal at a fixed photon energy for the sample, showing hysteresis loops observed at various temperatures, as marked in the figure.

Image of FIG. 4.
FIG. 4.

Upper panel: field dependence of MCD signal at a fixed photon energy for the CdMnCrTe samples with 1% and 3% Cr at 2 and 200 K. Lower panel: SQUID magnetization for CdMnCrTe sample with 1% Cr. Inset: field-cooled and zero-field-cooled temperature dependences of remanent magnetization measured by SQUID.
