摘要：

Magneto-excitation spectroscopy experiments are performed up to 5.5 T at low temperature (4.2 K) in a ZnSe/Zn0.73Mn1.27Se double quantum well structure. The experimental results are compared to calculations of the excitonic transitions, taking into account the strain effects, the giant Zeeman effect in the (Zn,Mn)Se layers, the diamagnetic shift of the exciton. We show that a magnetic-field induced transition in the nature of the fundamental excitonic state (from light to heavy hole exciton) occurs for a certain critical magnetic field.
