World’s thinnest magnet
Lawrence Berkeley National Laboratory, the University of California at Berkeley and others have developed what researchers say is the world’s thinnest magnet.
The one-atom-thin, two-dimensional (2D) magnet could one day pave the way towards new spin electronics or spintronics memory devices and other technologies in the market. Spintronics uses the orientation of an electron spin rather than a charge to encode data.
2D magnetic materials are promising. These materials enable exceptional spintronic capabilities. These capabilities are key for the development of next-generation memory and electronic devices.
For decades, the industry has attempted to develop thinner and smaller 2D magnets. The problem? 2D magnets tend to lose their magnetism and become unstable at room temperature.

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 memory devices, 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.

“We’re the first to make a room-temperature 2D magnet that is chemically stable under ambient conditions,” said senior author Jie Yao, a faculty scientist in Berkeley Lab’s Materials Sciences Division and associate professor of materials science and engineering at UC Berkeley.
