Abstract
Sawtooth quantum wells, in which the graded gap is produced by a linear variation in the concentration of a magnetic ion, offer a unique opportunity to investigate the additional optical transitions resulting from symmetry breaking. In the present theoretical work linear variations in the concentration of the magnetic Mn2+ ion in the Cd1-xMnxTe alloy permits a study of the variation of both the energy and oscillator strength of forbidden transitions as a function of the external magnetic field. The resulting variations in the symmetry of the system produces profound effects on the oscillator strengths of the Δn≠0 transitions.
