Iron-arsenic superconductors in class of their own

Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors. These findings - combined with iron-arsenide's potential good ability to carry current due to their low anisotropy - may open a door to exciting possible applications in zero-resistance power transmission.
