Time-resolved photoluminescence (PL). a The kinetics of the PL intensity (black solid line) and the degree of circular polarization of the PL (open orange circles) integrated in the spectral region of e-A0 at U = 0. Blue dashed line is a fit to the data. b Dependence of ρsA(U) of the FM proximity effect (full orange circles) and the position of the PL peak ħωmax(U) (open blue circles) on the bias voltage U. The solid curve is calculated using Eq. (8) with A = 17 %, U0 = 1.0 V, and U1 = 2.0 V. Error bars represent standard deviations
