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 Oak Ridge National Laboratory and Vanderbilt University are challenging conventional wisdom about superconductivity and magnetism
Oak Ridge National Laboratory will be home to two Energy Frontier Research Centers (EFRCs) announced this week by U.S. Energy Secretary Ernest Moniz.
