Tag: iron-based superconductors
Omar Chmaissem and Dennis Brown
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 the best known superconducting materials can operate only below 218 degrees Fahrenheit under...
