abstract = "We employed the reflective probing of linearly polarized light to explore the dependence of electron spin dynamics, in a high mobility dense two-dimensional electron gas, on the external magnetic field, excitation power and sample temperature using the time-resolved Kerr rotation. Owing to the complex layered structure, the dynamics of spin polarization in the studied sample enclosed information about the spin signal corresponding to the different populations of electrons. Fit to the data revealed multiperiodic spin precession, with distinct g-factors that modulate the decay of the TRKR envelope. Additionally, the spin precession in our structure was seen to be thermally robust, persisting up to 250 K. The dynamics of optically induced spins, from different electron populations, was monitored as a function of different experimental parameters.",
