Editor's note: This article will appear in the June 2008 issue of Scientific American.For more than 20 years, the only known superconductors that worked far above liquid-helium temperatures were a few dozen compounds--virtually all based on copper. Now scientists have discovered the first high-temperature superconductors based on iron. These novel materials could help unravel one of the biggest mysteries in science--how exactly the high-temperature versions work. [More]
