Magnetoelectric (ME) coupling in layered structures of magnetostrictive and piezoelectric phases are mediated by mechanical deformation and depends strongly on the interface conditions. Ni -lead zirconium titanate- Ni trilayers with neither electrodes nor bonding layers have been derived by electroless deposition. The structure of the electroless deposited Ni layer was characterized by X-ray diffraction. The cross-section of the Ni/PZT layers was investigated using scanning electron microscopy. The value of ME voltage coefficient (αE,31) increases as the interface roughness increases. The maximum of αE,31 for the Ni/PZT/Ni trilayers polarized after electroless deposition is higher than that for the Ni/PZT/Ni trilayers polarized before electroless deposition. It is essential to optimize the interface and the polarization to obtain higher ME voltage coefficient.

Magnetoelectric (ME) nickel and lead zirconium titanate multi-layers with neither electrodes nor bonding layers was developed by electroless deposition. Scanning electron microscopy reveals that the Ni layer is in direct contact with the PZT layer without inter-layer not only in Ni /PZT/ Ni trilayer but also in Ni /PZT/ Ni /PZT/ Ni multi-layer. The in-plane parallel magnetostriction has been measured for electroless deposited Ni . The saturation magnetostriction is 32.6 × 10-6. When the total thickness of multi-layers is the same, the ME voltage coefficient α E,31 decreases with increasing the stacking periodicity. On condition that the thickness of each layer is the same, the ME voltage coefficient V E,31 of the Ni /PZT/ Ni /PZT/ Ni multi-layer is nearly twice higher than that of the Ni /PZT/ Ni tri-layer at the resonance frequency, which provides a new choice to obtain higher ME voltage coefficient.
