Resumo

Ferromagnetic influence of a thin (~8 nm) surface CoPt layer on the circular polarization of the InGaAs/GaAs quantum well photoluminescence is observed in structure GaAs/InGaAs/GaAs/Al₂O₃(1 нм)/CoPt with narrow GaAs spacer d_S = 5 nm, while electroluminescence is polarized in the whole range of d_S = 5–100 nm. It is suggested that the short-range proximity effect is determined by overlap of electrons wave functions with the nearby ferromagnetic CoPt film.
