Pseudo Gap Superconductors...

Argonne National Laboratory
Thanks to a new study by the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors. The riddle involves a phenomenon called the “pseudogap,” a region of energy levels in which relatively few electrons are allowed to exist.

Despite their name, high-temperature superconductors are actually quite cold – roughly 250 degrees to 350 degrees below zero Fahrenheit. Conventional superconductors, like those used in MRI machines or particle accelerators, are even colder. Even though they are still quite cold, high-temperature superconductors are of special interest to researchers because, at least in theory, they are much easier to keep sufficiently cold and are thus potentially more useful.
