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.

SS模式双层复合材料正反磁电效应的综合分析

摘要 剪切剪切（SS）模式磁电（ME）复合材料的实验研究很少，尤其是在共振频率附近，因为其制样复杂，共振频率高。此外，关于SS模式磁电复合材料的理论研究仍是空白。在本文中，提出了一个等效电路模型来分析 SS 模式 ME 双层复合材料中的正反磁电（DME 和 CME）效应。然后，对复合材料进行了实验研究，显示出与理论预测的良好一致性。在 1800 Oe 直流磁场下，这种简单的双层复合材料的 SS 模式具有显着的场灵敏度和高得多的 DME 和 CME 系数，分别达到 27.5 V/(cm·Oe) 和 3 × 10-6 s/m共振频率附近。
