Abstract:
Light emission from ZnMnTe/ZnMgTe structures with the quantum wells ZnTe containing monolayer manganese inclusions and quantum wells Zn$_{0.45}$Mn$_{0.15}$Te were investigated under the different excitation conditions. The heavy-hole exciton $\sigma^+$ and $\sigma^-$ magnetic components show the unusual behavior concerning their energy shifts and intensities. It is possible to explain the Zeeman splitting of the heavy exciton emission band if the following factors are taken into account. Firstly, ZnMnTe/ZnMgTe quantum well structures are of the type II due to the strains as concerns to the electron and heavy hole. Secondly, the electron and hole magnetic sublevels population is far from equilibrium due to the fast energy transfer from the electron- hole system to the 3$d$-shells of magnetic ions.
