摘要
Detailed investigations of steady-state photoluminescence (PL) in Cd(Mg,Mn)Te-based asymmetric double quantum wells (ADQW) have been performed in magnetic fields up to B=10 T. PL spectra are determined by mutual exciton band alignment of adjacent wells in spin-dependent ADQW potential. It is found that the populations of thermalized excitons in the wells are governed by intrawell spin relaxation, which allows to control spectral and polarization characteristics of sernimagnetic ADQWs by varying of excitation conditions and structure parameters.
