摘要

Magnetization manipulation by an electric field(E-field)in ferromagnetic/ferroelectric heterostructures has attracted increasing attention because of the potential applications in novel magnetoelectric devices and spintronic devices,due to the ultra-low power consumption of the process.In this review,we summarize the recent progress in E-field controlled magnetism in ferromagnetic/ferroelectric heterostructures with an emphasis on strain-mediated converse magnetoelectric coupling.Firstly,we briefly review the history,the underlying theory of the magnetoelectric coupling mechanism,and the current status of research.Secondly,we illustrate the competitive energy relationship and volatile magnetization switching under an E-field.We then discuss E-field modified ferroelastic domain states and recent progress in non-volatile manipula-tion of magnetic properties.Finally,we present the pure E-field controlled 180° in-plane magnetization reversal and both E-field and current modified 180° perpendicular magnetization reversal.
