Opis:: Effect of intensive interlevel transitions in quantum well and strong spin-orbit interaction on weak localization is considered. Anomalous magnetoresistance in classically weak fields is calculated for p-type quantum wells based on A$\text{}_{3}$B$\text{}_{5}$ semiconductors. It is shown that the sign of magnetoresistance changes with varying doping level and the role of the intersubband transitions in weak localization effects depends dramatically on a view of the scattering potential.

Opis:: Magneto-optical properties of type II heterostructures with InSb/InAs quantum dots has been studied at external magnetic field applied in the Faraday geometry. The emission polarization degree can be changed in the range from 100% σ-minus to 10% σ-plus due to excitation intensity and temperature variation. The detailed calculation of the band structure within a tight-binding approximation is presented. The simulation of the experimental data reveals that the oscillator strength of the optical transitions involving electrons with the spin oriented along and opposite to the magnetic field vector differs by approximately 1.8 times in the heterostructures under study.
