摘要：

The present paper describes new polar angle-dependent magneto-resistance (ADMR) measurements in the overdoped cuprate Tl2Ba2CuO6+delta over an expanded range of temperatures and azimuthal angles. These detailed measurements re-affirm the analysis of earlier data taken over a more restricted temperature range and at a single azimuthal orientation, in particular the delineation of the intraplane scattering rate into isotropic and anisotropic components. These new measurements also reveal additional features in the temperature and momentum dependence of the scattering rate, including anisotropy in the T-2 component and the preservation of both the T-linear and T-2 components up to 100 K. The resultant form of the scattering rate places firm constraints on the development of any forthcoming theoretical framework for the normal state charge response of high-temperature superconducting cuprates.
