“…4(a), a hysteresis loop with a rather symmetric butterfly shape is observed, which is consistent with the shape of strain vs electric field hysteresis loop and different from that of polarization vs electric field hysteresis loop of the PMN-PT substrate17. Thus the observed electric field manipulation of magnetization in SRO/PMN-PT heterostructure would be ascribed to the electric-field-induced strain.…”

“…Due to the lattice mismatch (~2.3%) between SRO and PMN-PT, the SRO film is under the substrate-induced tensile strain along the in-plane direction. Besides the epitaxial growth, the surface morphology of the film is also important for the efficiency of strain transferred from the substrate to the film in strain-mediated ME heterostructures17. The AFM image exhibited in Fig.…”

“…In magnetic-perovskite-based ME heterostructures, the magnetism can be manipulated by means of altering the magnetic anisotropy10, affecting the phase separation1112, or adjusting the spin state of magnetic ions13 through the electric-field-induced strain. In addition to strain-mediated mechanism, ferroelectric field-effect14 may also plays a role in tuning magnetic and transport properties of magnetic perovskites in those ME heterostructures due to the accumulation or depletion of charge carries at interface through ferroelectric polarization reversal151617. It is known that networks of corner-sharing oxygen octahedra play an important role in determining the magnetic and electronic properties of the perovskite through its deformations, rotations or tilts181920.…”

The electric field manipulation of magnetic properties is currently of great interest for the opportunities provided in low-energy-consuming spintronics devices. Here, we report the effect of electric field on magnetic and transport properties of the ferromagnetic SrRuO3 film which is epitaxially grown on Pb(Mg1/3Nb2/3)O3-PbTiO3 ferroelectric substrate. With the application of electric field on the substrate, the magnetization, Curie temperature and resistivity of SrRuO3 are effectively modified. The mechanism of the electric field manipulation of these properties is ascribed to the rotations of RuO6 oxygen octahedra caused by the electric-field-induced strain, which changes the overlap and hybridization between the Ru 4d orbitals and O 2p orbitals, resulting in the modification of the magnetic and electronic properties.

Magnetoelectric composites and heterostructures integrate magnetic and dielectric materials to produce new functionalities, e.g., magnetoelectric responses that are absent in each of the constituent materials but emerge through the coupling between magnetic order in the magnetic material and electric order in the dielectric material. The magnetoelectric coupling in these composites and heterostructures is typically achieved through the exchange of magnetic, electric, or/and elastic energy across the interfaces between the different constituent materials, and the coupling effect is measured by the degree of conversion between magnetic and electric energy in the absence of an electric current. The strength of magnetoelectric coupling can be tailored by choosing suited materials for each constituent and by geometrical and microstructural designs. In this article, we discuss recent progresses on the understanding of magnetoelectric coupling mechanisms and the design of magnetoelectric heterostructures guided by theory and computation. We outline a number of unsolved issues concerning magnetoelectric heterostructures. We compile a relatively comprehensive experimental dataset on the magnetoelecric coupling coefficients in both bulk and thin-film magnetoelectric composites and offer a perspective on the data-driven computational design of magnetoelectric composites at the mesoscale microstructure level.

Multiferroic heterostructures composed of complex oxide thin films and ferroelectric single crystals have aroused considerable interest due to the electrically switchable strain and charge elements of oxide films by the polarization reversal of ferroelectrics. Previous studies have demonstrated that the electric‐field‐control of physical properties of such heterostructures is exclusively due to the ferroelectric domain switching‐induced lattice strain effects. Here, the first successful integration of the hexagonal ZnO:Mn dilute magnetic semiconductor thin films with high performance (111)‐oriented perovskite Pb(Mg1/3Nb2/3)O3‐PbTiO3 (PMN‐PT) single crystals is reported, and unprecedented charge‐mediated electric‐field control of both electronic transport and ferromagnetism at room temperature for PMN‐PT single crystal‐based oxide heterostructures is realized. A significant carrier concentration‐tunability of resistance and magnetization by ≈400% and ≈257% is achieved at room temperature. The electric‐field controlled bistable resistance and ferromagnetism switching at room temperature via interfacial electric charge presents a potential strategy for designing prototype devices for information storage. The results also disclose that the relative importance of the strain effect and interfacial charge effect in oxide film/ferroelectric crystal heterostructures can be tuned by appropriately adjusting the charge carrier density of oxide films.
