(a) TRFR as a function of pump-probe delay for the Samples A–C at and . The carrier densities are indicated in the figure. Lines are fits using Eq. (1). (b) Larmor frequency as a function of . Line is a linear fit. (c) Spin coherence time as a function of at for the same samples. The symbols in (c) correspond to those in (b).
Temperature dependence of TRFR on Sample A. (a) Spin precession at three temperatures for . (b) follows a power law (dashed line) with temperature in the intermediate region of 30 to 150 K, with an exponent . Theoretical fit to the data for DP mechanism is shown as a solid line.
(a) TRFR at for the bulk Sample D. Line is a guide for the eyes. (b) Faraday rotation versus at and on Sample D showing multiple RSA peaks. Lines are Lorentzian fits. (c) obtained from RSA peak at , as a function of temperature for Sample D (filled circles) with results from Sample A (open circles) shown for comparison. The line is a theoretical fit of the DP mechanism for Sample D.
