摘要: We report a giant photoinduced Faraday rotation in $\mathrm{CdTe}/{\mathrm{Cd}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}\mathrm{Te}$ multiple quantum well structure when the laser frequency is tuned close to fundamental excitonic transition of and saturation sets in. At same time we observe stimulated emission buildup magnetization through photon spin recycling presence magnetic field which was analyzed by time-resolved linearly polarized pump probe technique. The also seen absence seeding using circularly beam.
