Direct and converse magnetoelectric effects in Metglas/LiNbO3/Metglas trilayers
Electromechanical and magnetoelectric properties of Metglas/LiNbO 3/Metglas trilayers
have been studied in the frequency range from 20 Hz to 0.4 MHz. A trilayer of Metglas/PMN-
PT/Metglas prepared in the same way was used as a reference. Though PMN-PT has much
larger charge piezocoefficients than LiNbO 3 (LNO), the direct magnetoelectric voltage
coefficient is found to be comparable in both trilayers due to the much lower dielectric
permittivity of LNO. The magnitude of the direct magnetoelectric effect in the LNO trilayers is …
