We studied long-range proximity effect in hybrid ferromagnet-semiconductor structure between the ferromagnetic (FM) semimetal magnetite (Fe3O4) layer and CdTe quantum well (QW) using time-integrated and time-resolved photoluminescence (PL) spectroscopy techniques. The magnetite FM layer and a CdTe QW are separated by a 10 nm thick (Cd,Mg)Te barrier. The proximity effect is manifested in the circularly polarized photoluminescence corresponding to the recombination of photoexcited electrons with holes bound to shallow acceptors in the QW induced by the FM layer.
