Hall effect and resistivity in underdoped cuprates

Abstract

The behaviour 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.
