Scientists capture a magnetic flip in 140 trillionths of a second

Schematic figure of rapid (~100 ps) non-thermal switching of magnetization in antiferromagnetic Mn3Sn (to be precise, the magnetic octupole consisted of manganese spins forming a Kagome-lattice configuration) using electrical current pulse. Credit: Kazuma Ogawa and Ryo Shimano 2025 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
