Abstract :
In this work, Pb(Zr0.53Ti0.47)O3-CoFe2O4 (PZT-CFO) composite films were deposited on platinum silicon substrate using conductive La0.5Sr0.5CoO3 (LCSO) as buffer layers. Both LSCO and PZT-CFO films were prepared via a chemical solution deposited method. The structure and morphology of the composite films were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). XRD results show that both Pb(Zr0.53Ti0.47)O3 and CoFe2O4 phase were detected in the composite films. It is observed that the composite films demonstrate good ferroelectric and magnetic properties simultaneously. The composite films for LSCO of 6 layers are found to have the best ferroelectric property with the enhanced ferromagnetization.
