摘要：

We report the results of four-wave-mixing experiments in GaAs quantum wells in a magnetic field. We find that the time evolution of the excitonic signal is strongly modified when a magnetic field is applied. Quantum beats, rotation of the echo polarization, recovery of the echo for cross-polarized exciting beams, and an increase in the dephasing times are observed.
