Abstract

We report the observation of a resonance in the microwave spectra of the real diagonal conductivities of a two-dimensional electron system within a range of similar to +/- 0.015 from filling factor v = 1/3. The resonance is remarkably similar to resonances previously observed near integer v, and is interpreted as the collective pinning mode of a disorder-pinned Wigner solid phase of e/3-charged carriers.
