Rethinking Physics: Scientists Discover a “Giant” New Twist on a 140-Year-Old Effect

Their results pave the way for developing advanced electronic devices that rely on nonmagnetic materials. For the first time, researchers in Japan have detected a giant anomalous Hall effect (AHE) in a material that is not magnetic. The breakthrough was made using high-quality thin films of Cd3As2, a Dirac semimetal, subjected to an in-plane magnetic [...]
