Abstract

Electron drag between two two-dimensional electron systems has been measured in intermediate magnetic fields (ℏ / τ < ℏ ω_c ∼ k_B T) with a relatively low electron density. We explore, in this sample, the unusual increase of drag in intermediate magnetic fields which was well characterized by a nearly temperature independent B³ dependence. The anomalous behavior of electron drag observed in higher density samples is found to persist for low sample density.
