Abstract:
Exciton luminescence in AlGaAs layers is studied under interband excitation by circularly polarized light. Curves of luminescence depolarization in a transverse magnetic field (Hanle effect) exhibit peaks arranged symmetrically about a point $H=0$. It is shown that this effect is attributable to crossings of fine-structure levels in the magnetic field. The exchange splitting of bulk exciton levels and also recombination and spin-relaxation times are determined from a comparison between theoretical and experimental dependences.
