“…Figure 2 shows XRD patterns of the treated and untreated Metglas samples. It can be clearly seen that the treated sample has a significantly high intensity peak at 2θ = 44.8 • which is corresponding to body-centered cubic α-Fe (JCPDS# 87-0722) [27], while the untreated one has a weak peak in the XRD pattern. It can be inferred that, during the heat treatment, the amorphous Metglas crystallines internally via the process of nucleation, nanocrystallization and phase change [35], and the grains are in nano-sized determined by Scheler's formula [36].…”

“…Meanwhile, great efforts have been made to improve the performance of piezomagnetic phase by annealing method and laser treatment, which can be regarded as heat treatment at different temperature profiles. For instance, Ma et al enhanced the ME coefficient of Metglas/PZT/Metglas L-T mode ME composites by optimized annealing method [27]. Soon afterwards, the ME coupling in L-T mode ME composites was greatly enhanced by laser treatment along with (1-1) connectivity of the ME composites, proposed by Chu et al and PourhosseiniAsl et al successively, which exhibited value as high as 7000 V Oe −1 cm −1 and 12 500 V Oe −1 cm −1 [28,29] at resonance frequency, respectively.…”

Laminated magnetoelectric (ME) composites consisting of magnetostrictive and piezoelectric materials have been investigated and proved to realize strong ME coupling, which shows great benefits to fabricate high sensitivity ME magnetic sensors. In this work, optimized L-T mode ME composites consisting of heat-treated Metglas ribbons and [110]-oriented Mn-doped 0.71Pb(Mg 1/3 Nb 2/3 )O 3 -0.29PbTiO 3 (Mn-doped PMN-PT) single crystal fibers were reported, which achieves giant ME coupling and ultrahigh ME electric field coefficient of 4.26 × 10 4 V cm −1 Oe −1 at the electromechanical resonance. The equivalent magnetic noise of the ME sensor based on the proposed ME composites is only 2.89 fT Hz −1/2 at the electromechanical resonance, which exhibits great prospect in the application of precision magnetic field detection. Based on the characterization of heat-treated Metglas samples and the finite element simulation of the ME composites, the improved performance of the ME composites and ME sensors can be attributed to the enhanced properties of heat-treated Metglas (higher piezomagnetic coefficient d 33,m , higher induced magnetic flux density and lower mechanical loss) due to the enhancement of nanocrystallization and the stronger magnetic flux concentration effect corresponding to the dimension of the Metglas ribbons.

“…64 Ma et al directly introduced a Metglas nanocrystalline phase (FeBSiC) into pristine amorphous Metglas by optimizing the crystallization annealing conditions (350°C, 5 min). 92 The α SME was 1.25 times higher than that of amorphous Metglas/PZT/Metglas. In the absence of H dc , the α ME values of the composite were 103 mV cm −1 Oe −1 and 15.5 V cm −1 Oe −1 at 1 kHz and at the f r of 146.4 kHz, respectively.…”

The wireless sensor network energy supply technology for the Internet of things has progressed substantially, but attempts to provide sustainable and environmentally friendly energy for sensor networks remain limited and considerably cumbersome for practical application. Energy harvesting devices based on the magnetoelectric (ME) coupling effect have promising prospects in the field of self‐powered devices due to their advantages of small size, fast response, and low power consumption. Driven by application requirements, the development of composite with a self‐biased magnetoelectric (SME) coupling effect provides effective strategies for the miniaturized and high‐precision design of energy harvesting devices. This review summarizes the work mechanism, research status, characteristics, and structures of SME composites, with emphasis on the application and development of SME devices for vibration and magnetic energy harvesting. The main challenges and future development directions for the design and implementation of energy harvesting devices based on the SME effect are presented.

“…Direct ME effect, which describe the appearance of an electric polarization P upon applying a magnetic field H, is usually evaluated by the ME voltage coefficient a ME [2]. It is well known that ME effect in composites is extrinsic, strongly depending on the intrinsic piezoelectric or piezomagnetic properties of constituents, and coupling interaction across magnetic-piezoelectric interfaces [3][4][5][6][7]. So it is an effective approach to optimize the ME coupling by choosing suitable composition, and even more, the vibration and coupling mode.…”
