Abstract
The sign reversal of the Hall voltage in the mixed state of high tempe rature superconductors is explained by the motion of antivortices in b undles of 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 t han other vortices.
