Time-resolved Hanle effect for the negatively charged InGaAs/GaAs quantum dots has been studied using various protocols of the excitation intensity modulation. The data obtained have been analyzed in the frame of original model of different behavior of longitudinal and transverse components of nuclear spin polarization. Such analysis of experimental results has allowed to determine the times of rise and decay of these components. Their dependences on magnetic field strength have been found quite different. The observed behavior of nuclear polarization could not be explained in the frame of existing phenomenological models.
