Scientific paper

We report on a simple calculation of the magnetotransport in cuprate superconductors, based on the nearly antiferromagnetic Fermi liquid (spin fluctuation) model. We find that the model explains all important features seen experimentally: the violation of K"ohler's rule, the close relationship between the Hall angle and the magnetoresistance, the temperature dependence of the first high field correction to MR and the doping dependence of the low field MR data. In addition, the estimated values of omega_c tau, calculated using parameters obtained from the NMR measurements, yield values in close agreement with those found experimentally for overdoped and optimally doped cuprates.
