Abstract
Coulomb drag between two parallel two dimensional electron gases has been measured at high magnetic fields in samples with two different layer spacings. As the layer filling factor deviates from ν = 1/2, we find that the magnitude of the drag is enhanced quadratically with Δν = ν - 1/2, and the curvature of the enhancement is insensitive to both the sign of Δν and the spacing between the layers. Our results suggest that the enhancement is not due to non-perturbative interlayer correlations.
