Abstract
Based upon the well-known normal-core model for flux lines in high-κ superconductors and by correctly taking into account the backflow current due to pinning forces, we analytically derived the longitudinal resistivity and the Hall resistivity as functions of magnetic field in the region of flux flow. The present results qualitatively explain all the essential features of recent experiments on . In particular, we demonstrate that the observed negative Hall resistivity at low magnetic field in certain high- superconductors can be explained in terms of the existence of pinning forces in the sample.
