Abstract

In dc transport measurements of two-dimensional electron systems containing a small charge density modulation in one direction, resonance structure in resistance is observed near filling factor 1/2. For a sufficiently well-controlled modulation amplitude, the magnetic field positions of these distinct resistance minima are consistent with values for a periodic magnetic modulation as predicted in a Chern-Simons fermion picture of v = 1/2.
