✦ Synopsis

We examine the current-induced magnetoresistance oscillations in high-mobility two-dimensional electron systems using the balance-equation scheme for nonlinear magnetotransport. The reported analytical expressions for differential magnetoresistivity at high filling factors in the overlapping Landau-level regime show good agreement with the experimental observation and the numerical calculation.
