Abstract
The normal-state magnetoresistance (MR) of 90-K and 60-K and 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 around the Fermi surface. The anomalous transverse MR in these cuprates is closely related to the temperature dependence of the Hall angle.
