Magnetoelectric effects in layered samples of lead zirconium titanate and nickel films

The resonance enhancement of magnetoelectric (ME) interactions due to bending and radial modes are reported in structures consisting of nickel films deposited onto lead zirconate titanate (PZT). The ME voltage vs. frequency profiles have been obtained on samples with Ni layer thickness ranging from 1 to 100 μm. The mode frequencies and strength of ME interactions are found to increase linearly with increasing thickness of Ni. Theoretical mode frequencies are in very agreement with measured values.
