Query: The thermally activated motion of vortex bundles and the anomalous Hall
  effect in type-II conventional and high-Tc superconductors   The anomalous Hall effect in type-II conventional and high-Tc superconductors
is investigated based on the proposed novel theory of the thermally activated
motion of vortex bundles over a directional-dependent energy barrier. Our
calculations demonstrate clearly that anomalous Hall effect is induced by the
competition between the Magnus force and the random collective pinning force of
the vortex bundle. The Hall as well as the longitudinal resistivity for
constant temperature and constant applied magnetic field of type-II
superconducting films and bulk materials are calculated. The reentry phenomenon
is also investigated. All the results are in good agreement with the
experiments.
