Professor An Hongyu's team achieves controllable anomalous Hall effect in heavy metal/ferromagnetic insulator heterojunctions
Ferromagnetic insulators have attracted much attention in spintronics research due to their advantages such as no ohmic loss and low damping coefficient. However, due to the fact that charges are only transferred within heavy metals, revealing the origin of the anomalous Hall effect (AHE) in heavy metal/ferromagnetic insulator heterojunctions and regulating its AHE is challenging.Professor An H...
