Red, blue, and yellow spheres represent cobalt, oxygen, and zinc atoms, respectively. view more Credit: Berkeley Lab The development of an ultrathin magnet that operates at room temperature could lead to new applications in computing and electronics - such as high-density, compact spintronic memory devices - and new tools for the study of quantum physics. The ultrathin magnet, which was recently reported in the journal Nature Communications , could make big advances in next-gen memories, computing, spintronics, and quantum physics. It was discovered by scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley.
