Abstract
The behavior of the Hall ratio ${R}_{H}(T)$ as a function of temperature is one of the most intriguing normal-state properties of cuprate superconductors. One feature of all the data is a maximum of ${R}_{H}(T)$ in the normal state that broadens and shifts to temperatures well above ${T}_{c}$ with decreasing doping. We show that a model of preformed pairs-bipolarons provides a selfconsistent quantitative description of ${R}_{H}(T)$ together with in-plane resistivity and uniform magnetic susceptibility for a wide range of doping.
