Just like people, materials can sometimes exhibit “multiple personalities.” This kind of unusual behavior in a certain class of materials has compelled researchers at the U.S. Department of Energy’s Argonne National Laboratory to take a closer look at the precise mechanisms that govern the relationships between superconductivity and magnetism.
