Abstract
The normal (Cd1-xMnxTe grown on CdTe) and inverted (CdTe on Cd1-xMnxTe ) interfaces are studied separately using a quantitative model of the Zeeman effect of excitons in asymmetric CdTe quantum wells with a magn etic Cd1-xMnxTe barrier on one side and a nonmagnetic Cd1-yZnyTe barri er on the opposite side. The extrinsic effect (dilution of Mn) is domi nant at the inverted interface, while the normal interface allows a ra ther low upper bound to the intrinsic interface effect (due to missing nearest neighbors). Experimental results agree well with model profil es assuming a complete Cd/Mn exchange during growth between the surfac e layer and the subsurface layer.
