The anomalous Hall effect is examined using guided vortex motion in patterned high-Tc superconducting thin films. Rows of micrometer holes (antidots) affect the direction of flux motion in Hall arrangements. This allows to distinguish between different contributions to the Hall signal. We demonstrate, that the anomalous Hall effect is not caused by normal charge carriers, but rather by vortex motion antiparallel to the applied current. This is demonstrated by the suppression of the anomalous Hall effect in the case of guidance of vortices perfectly perpendicular to the applied current. It is concluded that the Magnus force being a force on the vortices that would contain a transverse component might be responsible for the anomalous Hall effect.
