The scaling law of the pinning force and anomalous Hall effect in the high-Tc superconductors

A novel approach to evaluating the pinning force in superconductors is developed on the basis of the extended model of thermally activated depinning. Our method expresses in a unified manner the influence of temperature, magnetic field and current density upon the pinning force acting on the flux. It explains the resistive behaviour, the scaling law of pinning force and the anomalous Hall effect in the mixed state of the superconductors. (authors)author)
