Ordered magnetic phase in Cd 1− x Mn x Te/Cd 1− y− z Mg y Zn z Te:N heterostructures: magnetooptical studies

Photoluminescence magnetospectroscopy is employed to examine the low-temperature magnetic phase that is induced by the carrier-mediated ferromagnetic exchange interaction in modulation-doped Cd1−xMnxTe quantum well. Unusual properties of the domain structure are linked to tendency towards spin-density wave formation in this low-dimensional magnetic system. ? 2000 Elsevier Science B.V. All rights reserved.
