Superconductor Theory

[PolyGirl]

Just another little piece of the puzzle (maybe):

From Physorg the article "Secrets behind high temperature superconductors revealed" does not state much other than "magnetism is involved in the mechanism behind high temperature superconductivity."

I believe the original article is from "Dr Alan Drew of the Department of Physics, Queen Mary, University of London". Physorg does not site the original article.

However, this article only basically states that "in both cases superconductivity emerges from a magnetic state." This comes from the "Publishing in Nature Materuals [2]", The article is listed at the botton of the article.

Superconductors, materials that carry electricity without resistance, can be divided into two broad groups depending on how they react to a magnetic field--or so physicists thought. New experiments show that one well-studied superconductor actually belongs to both groups at the same time. "If the experiment is true, this would add a whole new class of superconductors," says Egor Babaev, a theorist at the University of Massachusetts, Amherst.

The effect was found in MgB.
