摘要：

The nature of magnetoelectric (ME) interactions has been investigated under a dc electric field E in Ni-lead zirconante titanate bilayer for bending and acoustic modes. Both the ME voltage and the resonance frequencies are sensitively dependent on E and are attributed to variations in the permittivity and piezoelectric coefficient. A 40% increase in the ME voltage and 12% increase in the resonance frequency in comparison to zero bias were observed for bending modes. A similar behavior was observed for ME coupling at acoustic modes. The results are of interest for enhancing the sensitivity of magnetic field sensors based on ME composites.
