Abstract
We report on the spin-flip Raman scattering of electrons bound to shallow donors in single quantum wells of Te between Te barriers. An enhancement of the scattering intensity of the bound magnetic polaron was found for narrow quantum wells. A variational treatment of the quantum well exciton in combination with the polaron model developed for bulk material is applied to interpret the experimental observations. The reduced symmetry of the quantum well states manifests itself through the observation of new resonances in the Raman scattering cross section. A simple model taking into account the anisotropy of the Zeeman effect of the valence band can reproduce the observations.
