Abstract
We study the current scaling of the oscillatory magnetoresistance peak height in microwave induced magnetoresistance oscillations, over the temperature range 0.35 ≤ T ≤ 1.25 K, by examining the change in response observed under a supplementary I_DC current bias, when the I_DC also produces an overall giant negative magnetoresistance in the high mobility GaAs/AlGaAs system. A “universality” is observed in the decay of the magnetoresistance peak height over the examined temperatures, sizes, and applied I_DC. The results suggest that the photoexcited resistance maxima are sensitive not to the DC current, but rather to the current density j_DC = I_DC/W.
