Abstract

A flattened V3Si multifilamentary conductor was prepared by cold-rolling a wire-composite, and then changes in morphology and configuration of the superconductor — normal metal (S-N) interface and grain boundaries were induced. Correlation between microstructure and the angular dependence of Jc with respect to the transverse field direction indicates clearly the existence of two kinds of pinning centers. The S-N interface acts as a dominant pinning center for parallel fields and becomes important in low magnetic fields, in particular for composites with fine V filaments. The element pinning force of the S-N interface was estimated from Fp vs (V3Si layer thickness)-1 relationship.
