The results of femtosecond four-wave mixing experiments in bulk GaAs in high magnetic field are presented. At high magnetic field and low density, our measurements are dominated by features that cannot be explained by the semiconductor Bloch equations. These features are due to exciton-exciton correlations and are accounted for by a calculation based on the χ3-truncation formalism.
