Results of the summarizing process for the arXiv paper: 1101.0251v2

The study investigates the photoluminescence (PL) of structures consisting of a 50 nm $Zn_{0.9}Be_{0.05}Mn_{0.05}Se$ semimagnetic barrier, a nonmagnetic intermediate barrier of thickness $d$ nm $Zn_{0.943}Be_{0.057}Se$, a 2.5 nm $ZnSe$ quantum well, and a 30 nm $Zn_{0.943}Be_{0.057}Se$ layer at a temperature of 1.2 K as a function of magnetic field ($B$) and thickness ($d$) of the intermediate barrier. The rate of shift in different PL bands under low and high magnetic fields is estimated, and the causes for the increase in shift rate from low to high magnetic fields are interpreted. The study presents peculiarities regarding the effect of the intermediate barrier on luminescence properties, where deformation caused by adjacent layers plays a crucial role in forming Mn complexes in the $Zn_{0.9}Be_{0.05}Mn_{0.05}Se$ layer. Furthermore, changes in band gap and donor/acceptor level energies due to biaxial compression caused by the intermediate barrier are analyzed, along with an appreciable change in the effect of giant Zeeman splitting on energy levels within the structure. The results indicate that not only does the intermediate barrier play an important role in determining luminescence properties but also significantly affects polarization and movement of energy levels within the quantum well exciton emission under magnetic fields, highlighting its potential use for future applications in spintronics and optoelectronics technologies.
