Abstract
Two qualitatively different e-h systems have been investigated in undo ped CdTe/Cd0.88Mn0.12Te and Cd0.97Mn0.03 Te/Cd0.75Mn0.25Te QWs at 2 K and magnetic fields up to 14 T, namely a strongly spin-depolarized sys tem in the CdTe QW and a highly spin-polarized one in the Cd0.97Mn0.03 Te QW. The interaction of the spin-aligned excitons is repulsive. In contrast, in the spectra of a dense spin-depolarized excitonic system an additional well pronounced emission line M was observed at approxim ately 5 meV below the excitonic line. This line is assigned to the emi ssion of molecules consisting of excitons with opposite spins of both electrons and holes.
