Hall effect and resistivity in underdoped cuprates
Abstract
The behaviour of the Hall ratio RH(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 RH(T) in the normal state that broadens and shifts to temperatures well above Tc with decreasing doping. We show that a model of preformed pairs-bipolarons provides a selfconsistent quantitative description of RH(T) together with in-plane resistivity and uniform magnetic susceptibility for a wide range of doping.
