We investigate the possibility of observing the anomalous Hall effect in paramagnetic two-dimensional systems. We apply the semiclassical equations of motion to carriers in the conduction and valence bands of wurtzite and zinc-blende quantum wells in the exchange field generated by magnetic impurities and we calculate the anomalous Hall conductivity based on the Berry phase corrections to the carrier velocity. We show that under certain circumstances, this conductivity approaches one-half of the conductance quantum. We consider the effect of an external magnetic field and show that for a small enough field the theory is unaltered.
