Abstract

We studied the temperature dependence of nonlinear magnetoresistivity oscillations in high-mobility two-dimensional electron systems using a current-sweep method in a temperature range from 1.5 to 4.0 K. Consistent with previous studies we found that the primary source of the oscillation decay with increasing temperature is the modification of the quantum scattering rate entering the Dingle factor. These results provide further evidence that the high temperature decay of magnetoresistance oscillations appearing in the second order of the Dingle factor originates primarily from the electron-electron interaction effects.
