Abstract
There are few experimental studies on the shear-shear (S-S) mode magnetoelectric (ME) composites, especially near the resonance frequency because of their complex sample preparation and high resonance frequency. What’s more, theoretical studies on the S-S mode magnetoelectric composites is still blank. In this article, an equivalent circuit model was proposed to analyze the direct and converse magnetoelectric (DME and CME) effects in an S-S mode ME bilayered composite. Then, the composite was experimentally studied, showing a good agreement with the theoretical predication. The S-S mode has a remarkable field sensitivity and much high DME and CME coefficients, reaching 27.5 V/(cm·Oe) and 3 × 10-6 s/m, respectively, in this simple bilayered composite under the DC magnetic field of 1800 Oe near the resonance frequency. The composite shows a prospect of applications in high frequency ME transducers, energy capture devices and magnetic field sensitive sensors.
