We calculate the Hall coefficient and the magnetoresistance of an interacting two-carrier system. Our results, derived from two simple coupled kinetic equations, are identical to those obtained from the coupled Boltzmann equations. Specializing to a semimetal, we calculate RH and as a function of doping and pressure. We find that a strong electron-electron interaction has a large effect on these quantities. © 1979 The American Physical Society.
