Abstract

A novel mechanism for the sign change of the Hall effect in flux flow region is proposed. The difference δn between the electron density at the center of the vortex core and that far outside the vortex causes the additional contribution to the Hall conductivity δσxy = -δnec/B. This contribution can be bigger that the conventional one in the dirty case Δ(T)τ < 1. If the electron density inside the core exceeds the electron density outside the core the double sign change may occur as a function of temperature and magnetic field.
