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...

Northern Illinois University physics professor Omar Chmaissem, an NIU alumnae and a current postdoctoral student are key members of a team of scientists at the U.S. Department of Energy’s Argonne National Laboratory shedding light this week on the mysteries of superconductivity. In a study published today in “Nature Communications,” the team announces the discovery of...
