Abstract
Electric-field control of magnetism is presently among the most thriving research areas. However, in artificial, interface-controlled magnetoelectrics electric field is efficiently screened within a few monolayers of surface atoms, thus severely limiting the magnitude of magnetoelectric coupling. To strengthen magnetoelectric phenomenon at the interface it is proposed here to use either reversible surface chemistry or reversible bulk ion-exchange as tools to control magnetization response. The expected advantages are twofold; firstly, a complete on-and-off magnetism can be foreseen even for strong ferromagnets; secondly, the concept can go beyond the simple electrostatic charging at the surface/interface. The idea stems from supercapacitors and rechargeable batteries where reversible charging-discharging has been demonstrated for thousands of cycles.
