Space‐Charge Control of Magnetism in Ferromagnetic Metals: Coupling Giant Magnitude and Robust Endurance (Adv. Mater. 8/2023)

Magnetoelectric Coupling In article number 2207353, Chen Ge, Qiang Li, and co-workers propose a space-charge mechanism, through decoupling the transport of ions and electrons, to achieve magnetoelectric coupling in ferromagnetic-metal films. This method combines the advantages of both carrier doping and chemical reaction mechanisms, which allows for an efficient modulation with both large-magnitude and robust endurance.
