✦ Synopsis

The sign reversal of the Hall voltage in the mixed state of high temperature superconductors is explained by the motion of antivortices in bundles ot the vortex lattice. In the frame of the Kosterlitz-Thouless mechanism of vortex-antivortex pair generation in 2-D superconductors, it is shown that the antivortex moves with a much larger Hall angle than other vortices.
