摘要：

Transport studies on double-layer two-dimensional electron systems in GaAs double quantum wells have revealed quantum Hall states at total filling fraction nu = 1/2 and nu = 1. We conclude that these states arise from interlayer Coulomb correlations, based on studies of samples with different densities and layer separations and experiments utilizing tilted magnetic fields.
