Abstract
We have investigated the influence of the correlations between carriers on the magnetoresistance $\ensuremath{\beta}$ of metals. Using the expressions derived by Fletcher and Larson, the change in $\ensuremath{\beta}$ is evaluated for a one-band model. We have also used Landau's theory of a Fermi-liquid as modified by Silin to apply to the conduction electrons in a metal. The change in $\ensuremath{\beta}$ both in a one-band and in a two-band model is considered. It is found that for a semiconductor like InSb the change would be negligible, but that for a metal such as Al there would be a change of about ten percent.
