Multiferroic Pb(Zr0.52Ti0.48)O3–Co0.9Zn0.1Fe2O4 bilayer thin films via a solution processing.

Bilayer multiferroic nanocomposite films of Pb(Zr0.52Ti0.48)O3 (PZT) and Co0.9Zn0.1Fe2O4 (CZFO) were prepared on general Pt/Ti/SiO2/Si substrate via a simple solution processing. Different growth sequences of PZT and CZFO on the substrate yielded two kinds of bilayered structures, i.e., PZT/CZFO/substrate. and CZFO/PZT/substrate. Structural characterization by x-ray diffraction and electron microscopies showed good surface morphology and interfaces of these bilayered thin films. Strong ferroelectric and ferromagnetic responses were simultaneously observed in the bilayered thin films, depending on their structures. [ABSTRACT FROM AUTHOR]
