Abstract
We observe the huge longitudinal resistance (HLR) anomaly at filling factor Image in a separately contacted, 15 nm wide double quantum well structure. With drag measurements we probe the interlayer momentum transfer with one of the wells in the HLR state and observe a dependence of the drag on the filling factor ν in the drag layer. The interlayer momentum transfer peaks at Image and Image and is small for other filling factors.
