We report an experimental study of the excitonic spin relaxation dynamics in GaAs/AlGaAs Multiple Quantum Wells (MQW) presenting interface roughness by time and polarization resolved luminescence spectroscopy. The relaxation is found to occur mainly when the excitons are in the free state, before th
