"What's new about our work is that it showed how large this effect actually is in the new high-temperature super-conductors. We showed that the new materials are different in a nontrivial way from the low-temperature superconductors. The first paper was the first to show how easily observed the phenomenon is and focused on a bismuth-cuprate compound. The second paper reported a related experiment that approached this same problem from a different (microscopic) point of view.
"These investigations have brought this topic to the attention of many researchers in the field. Now there is hardly a conference on superconductivity that does not have a session devoted to the topic of flux motion. The reason is twofold. First, there is interest in the physics itself. These are truly intrinsic properties of the new materials. Second, the work opened the eyes of many to a new reality relating to potential applications of the ...
