Zusammenfassung

We have measured the low temperature magneto-drag between two two-dimensional electron gases (2DEGs). At matched densities, minima at odd filling factor are observed down to fields at which the Zeeman energy is only one tenth of temperature. At mismatched densities a novel 1/B periodic oscillation in the magneto-drag is observed with frequency h/2e times the density mismatch between the 2DEGs. ...
