Abstract

Magnetotransport measurements on the overdoped cuprate La1.7 Sr0.3 CuO4 are fitted using the Ong construction and band parameters inferred from angle-resolved photoemission. Within a band picture, the low-temperature Hall data can only be fitted satisfactorily by invoking strong basal-plane anisotropy in the mean free path. This violation of the isotropic- approximation supports a picture of dominant small-angle elastic scattering in cuprates due to out-of-plane substitutional disorder. We conjecture that both band anisotropy and anisotropy in the elastic-scattering channel strongly renormalize the Hall coefficient in La2-x Srx CuO4 across the entire overdoped regime.
