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.

LOS ALAMOS, N.M., April 19, 2021 A recent series of experiments at the National High Magnetic Field Laboratory (National MagLab) at Los Alamos National Laboratory leveraged some of the nation s highest-powered nondestructive magnets to reveal an exotic new phase of matter at high magnetic fields. The experiments studied the unusual Kondo insulator ytterbium dodecaboride (or YbB12) and were the first results from the new 75-tesla duplex magnet housed at the National MagLab s Pulsed Field Facility at Los Alamos.
