Neutrons piece together 40-year puzzle behind iron-iodide’s mysterious magnetism – Phys.org

Advanced materials with more novel properties are almost always developed by adding more elements to the list of ingredients. But quantum research suggests some simpler materials might already have advanced properties that scientists just couldn’t see, until now.
Researchers from Georgia Tech and the University of TennesseeKnoxville uncovered hidden and unexpected quantum behavior in a rather simple iron-iodide material (FeI2) that was discovered almost a century ago. The new research insights into…
