Abstract

Peculiarities in the dependence of the photoluminescence polarization of (In,Ga)As/GaAs quantum dots on the transverse magnetic field were observed under radio frequency (RF) field application. We show that these peculiarities result from the suppression of dynamical polarization of the 71Ga and As nuclei by the RF field. The effect of quadrupole splittings on the nuclear spin dynamics has been evaluated.
