| We observe a strong anisotropy of spin relaxation and a decrease in the spin relaxation rate with increasing electron mobility in contrast to predictions of the classical D'yakonov--Perel spin relaxation model. We show that for high electron mobility the cyclotron motion causes an additional modulation of spin--orbit coupling, leading to an effective suppression of the spin relaxation rate. |
