Summary

Story summary

Researchers in Japan have discovered a giant anomalous Hall effect (AHE) in nonmagnetic Cd3As2 thin films, challenging prior beliefs.
This effect is driven by orbital magnetization rather than spin, expanding understanding in condensed matter physics.
The findings, published in Physical Review Letters, may enhance electronic devices and sensor technologies.
The study was led by Associate Professor Masaki Uchida from the Institute of Science Tokyo.
