Magnetoelectric thin film composite of PZT/Co-Fe magnetic alloy bilayer

Magnetoelectric composite composed of PZT as a piezoelectric material and Co-50%Fe magnetic alloy as a magnetostrictive alloy produced by deposition of PZT layer on magnetic alloy via sol gel spin coating process. The samples were subjected to characterization using X-ray diffractometry and SEM techniques and electrical measurements. The results show that the PZT film exhibit a single perovskite phase and fully dense microstructure without any crack and voids. The prepared PZT films demonstrated good dielectric properties and have large potential applications in multifunctional devices. Based on acceptable electrical and magnetic properties, εr and tanδ, 894 and 0.12 respectively and magnetostriction coefficient of 70×10-6, it seems that these samples will have also good magnetoelectric properties.
