   Abstract:
   Time‐resolved four‐wave mixing is used to study electron scattering in modulation‐doped GaAs quantum wells in high magnetic fields up to 8T. A strong increase in dephasing times in strong magnetic fields is observed and attributed to a decrease in the scattering rates relative to zero field. An early time signal in high magnetic field is found, which is due to a polarization interaction process. A strong enhancement of the signal at the absorption edge is measured which is attributed to the Fermi edge singularity. Copyright © 1995 WILEY‐VCH Verlag GmbH & Co. KGaA
