Manufacturing Bits: Aug. 3 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. ....
UC Berkeley and Berkeley Lab develop 1-atom-thin 2-dimensional magnet Lisi Ludwig/Senior Staff UC Berkeley professor Jie Yao and his team developed a one-atom-thin two-dimensional magnet that reached the fundamental limit proposed by physicists years ago. Reaching the “fundamental limit” proposed by physicists years ago, UC Berkeley associate professor in materials science and engineering Jie Yao and his team created a thinner two-dimensional magnet. The Lawrence Berkeley National Lab, or Berkeley Lab, released a study published June 25 on the creation of the “one-atom-thin two-dimensional” magnet. The magnet, which operates at room temperature, will allow for a more efficient data encoding process, impacting the field of memory devices, computing, spintronics and quantum physics, according to the study. ....
Physicists Just Broke The Record For World s Thinnest Magnet, And It s Wild A slice of material just a single atom thick is breaking records. The ultra-thin wafer is a magnet that operates at room temperature, opening up avenues for the development of technology, particularly memory devices, and for research into ferromagnetism and quantum physics.
It s a huge step up from previous attempts to make a 2D magnet, which have lost their magnetism and stability when removed from ultracold conditions. We re the first to make a room-temperature 2D magnet that is chemically stable under ambient conditions, said materials scientist Jie Yao of the University of California Berkeley. ....
