Abstract
Filament isolation is an extremely important factor in multi-filament condu ctors. However, filament-bridging superconducting intergrowths have often b een observed. We show from magnetisation, transport and Hall probe experime nts on a range of BSCCO-2223 conductors that the effects of filament bridgi ng are substantial. We infer that the critical current densities within the intergrowths, and also across their grain boundaries, are extremely high.
