Description/Abstract We demonstrate that pinning strongly renormalizes both longitudinal and Hall resistivity in the flux flow regime. Using a simple model for the pinning potential we show that the magnitude of the vortex contribution to the Hall voltage decreases with increase in the pinning strength. The Hall resistivity {rho}{sub xy} scales as {rho}{sup 2}{sub xx} only for a weak pinning. On the contrary, a strong pinning breaks the scaling relation and can even result in a sign reversal of {rho}{sub xy} . (c) 1999 The American Physical Society.
