“…Such behavior is explained by the increase of the effective piezomagnetic coefficient until the optimum DC magnetic field is reached. With further increase in the DC magnetic field, a decrease in the induced voltage is observed for both composites resulting from the saturation of the magnetostriction coefficient [41][42][43] . Additionally, the ME response found for the CFO/P(VDF-TrFE) composites show an hysteretic behavior related to the magnetic hysteresis observed in Figure 3.…”

The manipulation of electric ordering with applied magnetic fields has been realized on magnetoelectric (ME) materials; however, their ME switching is often accompanied by significant hysteresis and coercivity that represents for some applications a severe weakness. To overcome this obstacle, this work focuses on the development of a new type of ME polymer nanocomposites that exhibits a tailored ME response at room temperature. The multiferroic nanocomposites are based on three different ferrite nanoparticles, Zn0.2Mn0.8Fe2O4 (ZMFO), CoFe2O4 (CFO) and Fe3O4 (FO), dispersed in a piezoelectric copolymer poly(vinylindene fluoride-trifluoroethylene) (P(VDF-TrFE)) matrix. No substantial differences were detected in the time-stable piezoelectric response of the composites (∼-28 pC·N(1-)) with distinct ferrite fillers and for the same ferrite content of 10 wt %. Magnetic hysteresis loops from pure ferrite nanopowders showed different magnetic responses. ME results of the nanocomposite films with 10 wt % ferrite content revealed that the ME induced voltage increases with increasing dc magnetic field until a maximum of 6.5 mV·cm(-1)·Oe(1-), at an optimum magnetic field of 0.26 T, and 0.8 mV·cm(-1)·Oe(1-), at an optimum magnetic field of 0.15 T, for the CFO/P(VDF-TrFE) and FO/P(VDF-TrFE) composites, respectively. In contrast, the ME response of ZMFO/P(VDF-TrFE) exposed no hysteresis and high dependence on the ZMFO filler content. Possible innovative applications such as memories and information storage, signal processing, and ME sensors and oscillators have been addressed for such ferrite/PVDF nanocomposites.

“…For example, the FeBSiC alloy (Metglas Inc.) has a relative permeability of about 40 000 due to its low magnetocrystalline anisotropy, and a saturation magnetostriction of about 30 ppm at H dc ∼ 10 Oe which yields notably higher piezomagnetic coeffi cient than Terfenol-D at low fi eld. [42][43][44] Recently, in a laminate of metglas ribbon and a PZT-fi ber actuator layer, greatly enhanced ME response up to about 10 V cm − 1 Oe − 1 at low frequency and several hundred V cm − 1 Oe − 1 at resonance under a low magnetic fi eld have been observed. [ 42 ] The large ME coeffi cients obtained in such metglas based ME composites inspire scientifi c interest and demonstrate an important direction for novel ME laminates.…”

Multiferroic magnetoelectric composite systems such as ferromagnetic-ferroelectric heterostructures have recently attracted an ever-increasing interest and provoked a great number of research activities, driven by profound physics from coupling between ferroelectric and magnetic orders, as well as potential applications in novel multifunctional devices, such as sensors, transducers, memories, and spintronics. In this Review, we try to summarize what remarkable progress in multiferroic magnetoelectric composite systems has been achieved in most recent few years, with emphasis on thin films; and to describe unsolved issues and new device applications which can be controlled both electrically and magnetically.
