Iron In The Mix - Science News

Iron In The Mix - Science News: In a paper published in Physical Review Letters in 2008, Singh and three other colleagues, including theorist Igor Mazin of the U.S. Naval Research Laboratory in Washington, D.C., suggested that pairing in iron-based superconductors is closer to pairing in cuprates than to that of traditional superconductors, yet is still different. Electrons maintain their distance, but there are no specific traveling directions that will break pairs apart. Such pairing differences could mean that the mechanism of superconductivity is not the same in the two families.
