Abstract

An understanding of the mechanisms that limit the critical current density in the Bi2223/Ag tapes is crucial to their viability in technological and commercial applications. Careful analysis of both transport and magnetisation measurements in an applied magnetic field, taken on the same samples, allow us to explore the regions of the H-T plane where either inter- or intra- granular properties dominate.<>
