NORMAL DOMAINS IN LARGE MULTIFILAMENTARY COMPOSITE SUPERCONDUCTORS

We study the dynamics of normal domains in a multifilamentary composit e superconductor with a large amount of stabilizer outside the multifi lamentary area. We consider the case when there is a transition layer with high thermal and electrical resistance between the superconductor and the stabilizer. We show the existence of localized and propagatin g normal domains in these composites. We derive an implicit expression for the propagation velocity of a normal domain.
