We report on experimental data of the drag effect between 2D electron gases confined to two separate layers in a strong perpendicular magnetic field. We investigate the coupling at Landau level filling factor Image as a function of temperature, carrier densities of the two layers and distance between them. A good agreement is found with a recent theory based on Coulomb interaction. Furthermore we ...
