Abstract

We report the high strength of magnetoelectric (ME) coupling of trilayered composites prepared by electro-deposition. The ME coupling of Ni-lead zirconate titanate (PZT)-Ni trilayered structure was measured ranged from1 kHz to 120 kHz. The trilayered composites exhibit high magnetoelectric voltage coefficient because of good bonding between piezoelectric and magnetostrictive layers. The maximum magnetoelectric voltage coefficient can be up to 33 V/cm Oe at the electromechanical resonance frequency. This magnetoelectric effect shows promising application in transducers for magnetoelectric energy conversion.
