Microstructural defects and superconducting critical currents in superconductors

OSTI ID:6978938
Superconducting critical current density is an extrinsic property of a superconductor and depends primarily on the interaction of crystal-structural defects and magnetic flux lines. The most effective characteristic defect size for the interaction is generally thought to be of an order of the superconducting coherence length. In order to understand critical current densities in the high temperature superconductors, the coherence lengths for some of metallic and oxide superconductors are listed and these are compared with the microstructural defects as observed by transmission electron microscopy. 42 refs., 7 figs.
