Abstract

The normal state transport properties (resistivity, Hall effect) of La2−xSrxCuO4 have been studied over wide ranges of Sr doping and temperature. The familiar T-linear resistivity and the strongly T dependent Hall effect RH(T) are found only near the optimal hole concentration (x ≈ 0.15–0.18). The charge dynamics changes significantly in the non-superconducting overdoped range with RH(T) becoming constant above a characteristic temperature T*, and p(T) ∝ Tn (n > 1; n ≈ 1.5±0.1). The temperature scale T*, decreasing with increasing hole concentration, provides a link between transport and magnetic properties.
