For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely.
​New measurements of atomic-scale magnetic behavior in iron-based superconductors by researchers at the Department of Energy’s 91°µÍø and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism
91°µÍø will be home to two Energy Frontier Research Centers (EFRCs) announced this week by U.S. Energy Secretary Ernest Moniz.
