“…These composites are acceptable for practical applications in a number of devices such as microwave components, magnetic field sensors and magnetic memories. For example, it was recently reported that the magnetoelectric composites can be used as probes in scanning probe microscopy to develop a near-field room temperature scanning magnetic probe microscope [32]. For the complete introduction of the magnetoelectric effects in composite materials, readers are referred to the review papers by Fiebig [25] and Nan et al [26], and hereafter we will no longer touch the magnetoelectric composite materials.…”

[Abstract] Multiferroics, defined for those multifunctional materials in which two or more kinds of fundamental ferroicities coexist, have become one of the hottest topics of condensed matter physics and materials science in recent years. The coexistence of several order parameters in multiferroics brings out novel physical phenomena and offers possibilities for new device functions. The revival of research activities on multiferroics is evidenced by some novel discoveries and concepts, both experimentally and theoretically. In this review article, we outline some of the progressive milestones in this stimulating field, specially for those single phase multiferroics where magnetism and ferroelectricity coexist. Firstly, we will highlight the physical concepts of multiferroicity and the current challenges to integrate the magnetism and ferroelectricity into a single-phase system. Subsequently, we will summarize various strategies used to combine the two types of orders. Special attentions to three novel a) E-mail: liujm@nju.edu.cn b) E-mail: renzh@bc.edu Multiferroics 2 mechanisms for multiferroicity generation: (1) the ferroelectricity induced by the spin orders such as spiral and E-phase antiferromagnetic spin orders, which break the spatial inversion symmetry, (2) the ferroelectricity originating from the charge ordered states, and (3) the ferrotoroidic system, will be paid. Then, we will address the elementary excitations such as electromagnons, and application potentials of multiferroics. Finally, open questions and opportunities will be prospected.

“…Among these functional materials, multiferroic materials have attracted very high interest234 due to their magnetoelectric (ME) property, namely the ability to control polarization by a magnetic field and magnetization by an electric field5. This feature makes them excellent candidates for electrically written and magnetically read memory technologies67, ambient sensors of magnetic field89, energy harvesting devices10, electrical field tunable devices11 and current/voltage converters12. During the past decade, the search for multiferroics with large magnetoelectric effect has become a prime focus of attention of physicists and material scientists.…”

The lead-free ferroelectric 0.5Ba(Zr0.2Ti0.8)O3 − 0.5(Ba0.7Ca0.3)TiO3 (BCZT) is a promising component for multifunctional multiferroics due to its excellent room temperature piezoelectric properties. Having a composition close to the polymorphic phase boundary between the orthorhombic and tetragonal phases, it deserves a case study for analysis of its potential for modern electronics applications. To obtain magnetoelectric coupling, the piezoelectric phase needs to be combined with a suitable magnetostrictive phase. In the current article, we report on the synthesis, dielectric, magnetic, and magnetoelectric characterization of a new magnetoelectric multiferroic composite consisting of BCZT as a piezoelectric phase and CoFe2O4 (CFO) as the magnetostrictive phase. We found that this material is multiferroic at room temperature and manifests a magnetoelectric effect larger than that of BaTiO3 −CoFe2O4 bulk composites with similar content of the ferrite phase.
