AbstractWe examine the radiation induced modification of the Hall effect in high-mobility GaAs/AlxGa1-xAs devices that exhibit vanishing resistance under microwave excitation. The modification in the Hall effect upon irradiation is characterized by (a) a small reduction in the slope of the Hall resistance curve with respect to the dark value, (b) a periodic reduction in the magnitude of the Hall resistance R-xy that correlates with an increase in the diagonal resistance R-xx, and
