In time-resolved Faraday rotation experiments, we have detected an in-plane anisotropy of the electron spin-dephasing time (SDT) in an n-modulation-doped GaAs∕Al0.3Ga0.7As single quantum well. The SDT was measured with magnetic fields of B⩽1 T, applied in the  and [11̅ 0] in-plane crystal directions of the GaAs quantum well. For fields along [11̅ 0], we have found up to a factor of about 2 ...
