Abstract

Lead zirconate titanate Pb(ZrxTi1-x)O3 (PZT) films with a composition x = 0.52 near the morphotropic phase boundary were deposited on dense CoFe2O4 (CFO) ceramic substrates using a chemical solution deposition. The PbO seeding layer was introduced to induce the (100) texture of PZT films. PZT film-on-CFO ceramic (PZT-CFO) composites with 2-layered PbO exhibits a (100) orientation degree of 0.62, while that for PZT-CFO composites without the PbO is only about 0.37. Accordingly, the ferroelectricity, dielectricity and magnetoelectric coupling in the PZT-CFO composites dramatically changes and the maximum ME coefficient exhibits great enhancement from 21.4 to 50.8 mV/cm·Oe.
