Abstract

We report on a strikingly linear behavior of the magnetoresistivity, ρ{variant}xx versus magnetic field B in two-dimensional electron systems at low-temperatures. While linearity of the Hall resistivity ρ{variant}xy versus magnetic field, punctuated in the region of the quantum Hall effect, is a direct consequence of the classical Hall geometry, there does not exist a theoretical basis for a linearity of ρ{variant}xx. The curious behavior of ρ{variant}xx is implicitly contained in a phenomenological relationship between ρ{variant}xx and ρ{variant}xy proposed earlier by Chang and Tsui. Our new data on very high mobility samples dramatically confirm their conjecture of this still unresolved proportionality between ρ{variant}xx and B dρ{variant}xy dB.
