On January 29, 2026 (Beijing Time), the prestigious international academic journal Nature published online a groundbreaking research achievement by the Physics Research Team at Fudan University. The study, titled "Ferromagnetic-Type Bistable Switching in Stoner-Wohlfarth Antiferromagnets," unveiled, for the first time, that a specific category of low-dimensional antiferromagnetic materials can display deterministic bistable bulk switching when subjected to an external magnetic field. This behavior mirrors that of ferromagnets, a phenomenon the researchers have aptly dubbed the 'collective dance.'

The team adeptly captured this phenomenon using their self-developed multimodal magneto-optical microscopy technique and further refined the classical theoretical framework of magnetism. This discovery represents a pivotal milestone in transforming antiferromagnetic material research from being perceived as 'interesting yet impractical' to 'readable and writable.' It opens up a new avenue for the development of next-generation, low-power, high-speed computing chips.
