Model of anisotropic scattering in a quasi-two-dimensional metal

A simple model of anisotropic scattering in a quasi-two-dimensional metal is studied. Its simplicity allows an analytic calculation of transport properties using the Boltzmann equation and relaxation time approximation. We argue that the c-axis magnetoresistance provides the key test of this model of transport. We compare this model with experiments on overdoped T1-2201 and find reasonable agreement using only weak scattering anisotropy. We argue that optimally doped T1-2201 should show strong angular-dependent magnetoresistance within this model and would provide a robust way of determining the in-plane scattering anisotropy in the cuprates.
