Effects of La0.5Sr0.5CoO3 buffer layers on the structure and properties of Pb(Zr0.53Ti0.47)O3-CoFe2O4 composite films

In this work, Pb(Zr_0.53Ti_0.47)O₃-CoFe₂O₄ (PZT-CFO) composite films were deposited on platinum silicon substrate using conductive La_0.5Sr_0.5CoO₃ (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(Zr_0.53Ti_0.47)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.
