Three distinct crystalline phases with different electronic, magnetic, and optical properties were reversibly induced in a material through the insertion and extraction of ions by an electric field at room temperature. Such multifunctional materials are desirable for many applications, from smart windows to spintronics. ... Read more »
Researchers have found a new way to control magnetism at the atomic level that will serve as a model for studying emergent phenomena in other systems. The ability to engineer and tune properties on such small length scales can (eventually) enable us to design exciting new magnetic devices. ... Read more »
Scientists working at the ALS have made the first unambiguous, direct measurements of ac spin currents flowing through nanostructured metal layers. The work represents a crucial step toward the development of future spintronic devices that are smaller, faster, and more energy efficient.
