Abstract
Hall effect measurements in the vortex state of the quasi two-dimensio nal (Q2D) organic superconductor kappa-(BEDT-TTF)(2)Cu(NCS)(2) are rep orted. The sign of the Hall conductivity changes with field and temper ature in the vortex state. The Hall conductivity is described as the s um of the two terms resulting from the quasiparticle (proportional to H) and the vortex motion (proportional to 1/H). The sign of the latter term depends on the current direction in Q2D plane. The behavior can be explained by the anisotropic motion of the charged vortex in the an isotropic Q2D plane.
