## Abstract We have studied the corrections to the Drude conductivity and Hall constant of a high‐mobility twodimensional electron gas in a GaAs/AlGaAs heterostructure due to the electron‐electron interaction in the presence of a mixed disorder. A parabolic, negative, temperature‐dependent magnetor
