We study the photoluminescence of diluted magnetic semiconductor CdMnTe/CdMgTe quantum well (QW) structures at low temperatures of 10 K using a Fourier imaging spectroscopy setup. It allows to observe the emitted lights intensity both angular and energy resolved. We demonstrate the coupling of QW exciton emission to surface plasmon polaritons close to the interface by observing a magnetic field induced change in emitted intensity. The effect decreases with increasing QW to surface distance.
