Abstract
The normal-state magnetoresistance (MR) Δρ/ρ of 90-K and 60-K YBa2Cu3O7-δ and La2-xSrxCuO4 (x=0.17) has been measured in the longitudinal (field H parallel to current J) and transverse (H c) geometries, with J in-plane. In all cases, the orbital component of the MR displays a temperature dependence that strongly violates Kohler's rule. We show that the classical orbital MR measures the variance of a local Hall angle θ(s) around the Fermi surface. The anomalous transverse MR in these cuprates is closely related to the temperature dependence of the Hall angle.
