Abstract

We have measured the small-signal AC response (from 300 kHz to 3 MHz) in the presence of a DC current in the reentrant insulating phase around Landau level filling factor ν = 1 5 in a high quality two-dimensional electron system in GaAs AlGaAs and observed a broad resonance on top of a background that changes from being capacitive at low currents to inductive at high currents. The resonance frequency which shows a sublinear dependence on the DC current, is interpreted as that of the washboard oscillations of the Wigner crystal.
