Fig. 4
Spin-flip Raman scattering (SFRS). a SFRS signal under resonant excitation of the A0X complex at a magnetic field BF = 10 T tilted by 20° with respect to the sample growth direction. Line h corresponds to a single acceptor hole spin-flip process, e+h is a double spin-flip process, and e is a spin flip of a conduction band electron. b Dependence of the Stokes shifts of the three lines on the magnetic field. c Dependence of the exchange constant Δpd on the applied voltage U for the hole bound to an acceptor (green solid circles) and the corresponding dependence of the energy of the PL peak ħωmax(U) (blue open circles). The solid curve is calculated from Eq. (8) with A = 175 μeV, U0 = 0.7 V, and U1 = 1.8 V. Error bars represent standard deviations
