“…As B n and ϕ red are considered continuous across ∂Ω m , the weak formulation in the free space domain can then be obtained by projecting (34) onto an appropriate virtual magnetic scalar potential field δϕ 0 associated with a closed surface ∂Ω corresponding here to the external surface ∂Ω m of the active material domain:…”

“…These models have shown how the volume fractions of each phase, the connectivity [30], as well as the piezoelectric, piezomagnetic and elastic properties participate in the ME coupling. The nonlinear response and stress dependence of the ME composite are addressed, for example, by Wang and Zhou [31], Lin et al [32], Burdin et al [33], Shi et al [34] who considered the nonlinear anhysteretic behavior and the effect of stress in the constitutive relationships of the ferromagnetic phase. It results from these approaches a way to improve the ME coefficients and the frequencymultiplying behavior of laminated composites via magnetic bias field and pre-stress.…”

“…The best magnetostrictive materials that prepare the highest piezomagnetic coefficients are Terfenol-D, Galfenol, and Metglas, whereas piezoelectric materials that are generally used are PZT, AlN, and PMN-PT [27][28][29][30][31]. Other factors such as the influence of vacuum, geometric design of sensors and electrodes, and electromechanical resonant (EMR) frequency also affect the sensitivity of these structures [32][33][34][35].…”

Ultrasensitive magnetic field sensors based on magnetoelectric (ME) structures have many applications in bio-magnetic sensors and magnetoencephalography (MEG) scanners. Enhance the sensitivity, limit of detection and main frequency of these sensors need simulation process by accurate methods such as finite element method (FEM). To get good sensitivity and efficient benefit, we use a cantilever-type composite structures including galfenol alloy as a magnetostrictive layer and AlN as a piezoelectric layer. Galfenol is an alloy of iron and gallium and its ${\text{Fe}}_{\text{0.83}}{\text{Ga}}_{\text{0.17}}$ structure has a high magnetostriction coefficient and can be used as a thin film. According to the cantilever structure, the maximum bending of the structure is 20 $\text{μm}$. The simulated sensor has a limit of detections of 1 $\raisebox{1ex}{$\text{pT}$}\!\left/ \!\raisebox{-1ex}{$\sqrt{\text{Hz}}$}\right.$ and can measure an AC magnetic field of 1 pT. This sensor has the best performance in the bias DC magnetic field of 2.3 mT and resonance frequency of 2521.8 Hz and has a magnetoelectric coefficient of 4865 ($\raisebox{1ex}{$\text{V}$}\!\left/ \!\raisebox{-1ex}{$\text{cm.Oe}$}\right.$).

“…Notably, this means a majority of strain-mediated magnetoelectric composites are brittle and rigid. Regarding composite configurations, the most popular is particulate-matrix, stack laminate, rod-matrix, and core-shell, also referred to as 0-3, 2-2, 1-3, and pseudo-1-D, respectively (Palneedi et al, 2016; Shi et al, 2021). Each configuration has different benefits; such as 2-2 composites being highly studied and easily modeled (Bichurin and Petrov, 2012; Chang and Carman, 2007; Hockel et al, 2011; Newacheck and Youssef, 2019b; Subhani et al, 2017; Truong and Roundy, 2020; Wang and Zhou, 2011; Zhou et al, 2016).…”

Achieving efficient magnetoelectric coupling of core-shell and particulate multiferroic composites has been a challenging hurdle; however, research has shown unwavering interest to overcome this barrier in pursuit of their implementation into promising potential applications. Herein, a fully coupled computational model of core-shell and particulate composites is developed and verified to investigate the magnetoelectric interactions of the particle and matrix on the microscale. The effects of particle geometry, settling, and agglomeration were exhaustively studied by investigating seven different shapes and a wide range of vertical and lateral particle spacing. Overall, it was found that utilizing particle geometries and positioning that closely resemble a laminate configuration, such as a prolate ellipsoid and horizontal particle alignment, enhances the magnetoelectric coupling of the composite structure. The results coincided with the experimental results concerning settling and agglomeration.
