The effect of structural defects in superconductors on the resistivity and Hall effect

We consider the effect of pinning centers on the motion of Abrikosov vortices in type II superconductors, and find the relationship between the observed voltage drop and the mean perturbation of the vortex trajectory as a result of one scattering act from the pinning center. The results of the suggested mechanism for the effects of pinning are compared with experiment.
