Abstract

This review article aims at illustrating the recent progresses in the electrical control of magnetism in oxides with profound physics and enormous potential applications. In the first part, we provide a comprehensive summary of the electrical control of magnetism in the classic multiferroic heterostructures and clarify their various mechanisms lying behind. The second part focuses on the novel route of electric double layer gating for driving a significantly electronic phase transition in magnetic oxides by a small voltage. The electric field applied on the ordinary dielectric oxide in the third part is used to control the magnetic phenomenon originated from the charge transfer and orbital reconstruction at the interface between dissimilar correlated oxides. At last, we analyze the challenges in electrical control of magnetism in oxides, both on mechanism and practical application, which would inspire more in-depth researches and advance the development in this field.
