A team led by Ryo Shimano at the University of Tokyo has directly observed how electron spins flip inside an antiferromagnet, a material in which opposing spins cancel each other out. By capturing this process in action, the researchers identified two separate switching mechanisms. One of them outlines a practical path toward ultrafast, non-volatile magnetic memory and logic devices that could outperform today’s technologies. The results were published in Nature Materials.
From punched paper cards and metal rods to vacuum tubes and transistors, modern computing has always relied on physical systems to represent 0s and 1s. As demand for processing power continues to rise, researchers are searching for faster and more efficient alternatives. Antiferromagnets offer a…
