Description

We have studied the broadened emission lines of CdTe/Cd0.75Mn0.25Te tilted superlattices (TSLs) in contrast to the sharp emission lines of the nonmagnetic CdTe/Cd0.74Mg0.26Te TSLs by using near-field scanning optical microscopy. The broadening of the photoluminescence (PL) spectra reflect the statistical fluctuation in the magnetization of Mn spins in the exciton magnetic polaron (EMP). The EMP PL strongly depends on the temperature; the line width of the EMP PL spectrum becomes narrow and the spatial distribution of the EMP PL intensity has been found to be reduced with rising the temperature from 5 to 11 K, because of annihilation of the EMP.
