Abstract
Inhomogeneous magnetic fields are used to exert a magnetic force on two-dim ensional excitons. The large field gradients are produced by positioning a thin magnetized stripe of dysprosium on top of a semi-magnetic CdMnTe/CdMgT e quantum well. By measuring the photoluminescence energy and intensity, sp atially resolved with mu m resolution, the actual value of the local magnet ic force, which can be as high as 0.4 meV/mu m, and its effect on the excit on motion are determined.
