Abstract
The discovery of a critical current density persisting out to high fields violates early expectations of weak‐link behavior in polycrystalline YBa2 Cu 3O7 and Bi‐based superconductors. Explanations in terms of non‐weak‐linked portions of grain boundaries or the brick‐wall model are assessed.Keywords
