Story summary

Researchers in Japan discovered a giant anomalous Hall effect (AHE) in nonmagnetic material using high-quality thin films of Cd3As2.
Led by Associate Professor Masaki Uchida, the study was published in Physical Review Letters on September 2, 2025.
They identified orbital magnetization as the AHE's source, challenging previous assumptions.
The team used molecular beam epitaxy and an in-plane magnetic field to measure Hall conductivity.
These findings may lead to advancements in electronic devices, such as more efficient Hall sensors.
