Scientists discover exotic magnetic structures in iron-based superconductors

Scientists from NIU and Argonne National Laboratory are reporting this week in the journal Nature Physics on the discovery of exotic magnetic structures in iron-based superconductors. Superconductors exhibit amazing properties: When cooled below certain temperatures, they conduct electricity without energy-sapping resistance. But
