We investigated the effective magnetic field induced by spin-orbit interaction in a gated modulationdoped GaAs/AlGaAs quantum well (QW) structure. We measured the precession of the optically injected electron spins at zero magnetic field by a time-resolved Kerr rotation (TRKR) technique as a functio
