Dislocation Inertial Model for the Increased Plasticity of the Superconducting State

Abstract

A model is proposed to account for the increased plasticity found for superconductors entering the superconducting state. It is supposed that at low enough temperatures in superconductors, inertial effects permit dislocations to overshoot their static equilibrium positions against obstacles and exert greater forces on the barriers. Quantitative agreement is found with experimental results for the temperature dependence of the stress drop. There is evidence that inertial effects contribute to the flow stress of nonsuperconductors.
