Abstract
In the development of multifunctional data storage devices, controlling magnetic properties by electric field would be highly desirable. This work reported the relationship of magnetic properties of MgO film on porous anodic alumina (PAA) substrates to the different resistance states of Ag/MgO/PAA/Al(Ag/MP/Al) device at room temperature. We suggest that the fully deterministic magnetic switching in this composite film is based on the high sensitivity of oxygen vacancy defect-based conductive filaments to electric field. Our review offers a convenient way to control the magnetic properties using electric field, and shows great promises for developing novel multifunctional material in the future.
