The viscous flux-flow effect on the pinning induced magnetostriction of type-II superconductors

Abstract

We have investigated the magnetostriction of type II superconductors under the viscous flux-flow. The critical state approach was employed to obtain the magnetostriction loops versus applied field. The flux profile equations in the time dependent form have been introduced for both exponential model and Anderson-Kim model. Both shape and scale of the curves are dependent on the frequency of applied field. © 2007 American Institute of Physics.
