“…Generally, any induced magnetization under action of external electric field is called as magnetoelectric effect. Magnetoelectric effect is observed in many multifunctional composites [11], however, its origin is different from that of our system.…”

“…The controllable capacitance or dielectric permittivity in magnetoelectric (ME) composites with external DC magnetic field, [1][2][3][4][5] which is known as magnetocapacitance (MC) effect, has a widely potential practical application, such as tunable spin filters, storage devices, and magnetic sensor. 4,[6][7][8] As reported in previous study, multiferroic ME materials possesses ferromagnetism, ferroelectricity and ferroelasticity simultaneously, 9,10 the direct method to assess the degree of ME coupling is based on ME effect, and another widely used characterization method is an indirect measurement of dielectric response to an applied field, which is called MC method.…”

In previous works, most of them employ a linear constitutive model to describe magnetocapacitance (MC) effect in magnetoelectric (ME) composites, which lead to deficiency in their theoretical results. In view of this, based on a nonlinear magnetostrictive constitutive relation and a linear piezoelectric constitutive relation, we establish a nonlinear model for MC effect in PZT-ring/Terfenol-D-strip ME composites. The numerical results in this paper coincide better with experimental data than that of a linear model, thus, it’s essential to utilize a nonlinear constitutive model for predicting MC effect in ME composites. Then the influences of external magnetic fields, pre-stresses, frequencies, and geometric sizes on the MC effect are discussed, respectively. The results show that the external magnetic field is responsible for the resonance frequency shift. And the resonance frequency is sensitive to the ratio of outer and inner radius of the PZT ring. Moreover, some other piezoelectric materials are employed in this model and the corresponding MC effects are calculated, and we find that different type of piezoelectric materials affect the MC effect obviously. The proposed model is more accurate for multifunction devices designing.

“…2 inset͒, consistent with the previous reports. [4][5][6][7][8] The reduction in A at higher frequency is related to the fact that there is already considerable elastic energy stored in the bimorph due to the stress. The relevant parameter of the clamped-clamped bimorph is the receptance, the amplitude displacement per unit force.…”
