Temperature dependences of spin coherence profiles in an intrinsic GaAs measured by cohelicity elliptically polarized pump-probe transmission change for five different temperatures of 8.1, 60, 110, 180, and at a photon energy of under a magnetic field of in Voigt geometry. The scattered circle points are experimental data while the solid lines are fittings to the experimental data by Eq. (1). Different offsets are added to each curve for clarity.
Temperature dependences of spin coherence and recombination lifetimes. The scattered circle points with error bars are experimental data. The solid line is the fitting to spin coherence lifetime by a relation . The dashed line is a best fit to recombination lifetime by a cubic polynomial for eye guide.
Temperature dependence of electron factor measured at a photon energy of .
