Abstract

Using a recently developed formalism for the weak-field Hall effect in 2D metals, we calculate the expected magnitude and temperature dependence of the Hall conductivity σ_xy and Hall coefficient R_Hall(T) directly in terms of Fermi surface parameters for two prototypical single band quasi-2D molecular superconductors: (TMTSF)₂PF₆ and β-(BEDT-TTF)₂I₃. The results, which are in good agreement with experiment, provide a new measure of the T- and k-dependent scattering time τ_k(T) on the Fermi surface.
