Abstract
We study the magnetotransport properties of a model of small-angle scattering in a marginal Fermi liquid. Such a model has been proposed by Varma and Abrahams [Phys. Rev. Lett. 86, 4652 (2001)] to account for the anomalous temperature dependence of in-plane magnetotransport properties of the high- cuprates. We study the resistivity, Hall angle, and magnetoresistance using both analytical and numerical techniques. We find that small-angle scattering only generates a difference in temperature dependence between the inverse Hall angle and the resistivity near particle-hole symmetric Fermi surfaces where the conventional Hall term vanishes. The magnetoresistance always shows Kohler’s rule behavior.
