Abstract
The exchange interactions between excitons and manganese ions in wide (80 nm) quantum wells of Cd1−xMnxTe (x≈0.0015 and x≈0.00027) have been measured for states with center of mass quantum numbers up to 10. The corresponding translational wave vectors are in the range up to 4×106 cm−1 and in this range we detect no systematic variation of the exchange parameter N0(α−β), which remains constant to within ±3%. The result is consistent with previous studies of the wave vector dependence of the electron contribution N0α but differs from previous observations of the wave vector dependence of exciton exchange interaction in quantum wells with much higher concentrations of manganese.
