Direct and converse magnetoelectric effects of sandwiched composites worked in shear-shear mode studied by uniform equivalent circuit

Abstract

There are few theoretical and experimental studies on shear-shear (S-S) mode magnetoelectric composites due to the complex shear vibration theories and high resonance frequency. In this article, a uniform equivalent circuit is proposed to analyze direct magnetoelectric (DME) and converse magnetoelectric (CME) effects of S-S mode sandwiched composites. The results show DME and CME changes of S-S mode are similar to that of L-T mode and L-L mode, but S-S mode has a higher DME coefficient near the resonance frequency. This research provides an effective theoretical method for the ME research and a route for the ME devices at high frequency.
