We have experimentally studied the spin-induced time reversal symmetry (TRS) breaking as a function of the relative strength of the Zeeman energy (EZ) and the Rashba spin-orbit interaction energy (ESOI), in InGaAs-based 2D electron gases. We find that the TRS breaking, and hence the associated dephasing time τ (B), saturates when EZ becomes comparable to ESOI. Moreover, we show that the spin-induced TRS breaking mechanism is a universal function of the ratio EZ/ESOI, within the experimental accuracy.
