DOIAbstract
The magnetic field induced type I - type II transition in a 20-Å-thick CdTe/Cd0.875Mn0.125Te single quantum well has been documented by the resonance light reflection measurements. The pronounced splitting of the lower Zeeman-component exciton resonance has been observed to appear at 1.5T and to increase at higher fields, which manifests the formation of direct and indirect exciton states in the type II quantum well
