Abstract
About 1.05 µm-thick Pb(Zr0.5Ti0.5)O3 (PZT) films containing Fe3O4 nanoparticles were deposited on LaNiO3-coated silicon substrates through a sol-gel technique. Fe3O4 nanoparticles were effectively dispersed into PZT solution under the involvement of polyvinylpyrrolidone. X-ray diffraction confirmed the coexistence of PZT and Fe3O4 phases without other impurity phases. Scanning electron microscope revealed that the thick composite films possess well-defined and crack-free microstructure. The composite films exhibit good ferroelectric and ferromagnetic properties at room temperature. An obvious magnetodielectric effect has been demonstrated in the Pb(Zr0.5Ti0.5)O3/Fe3O4 composite films. Magnetic field induced change in ferroelectric polarization loop may support the possible magnetoelectric coupling between PZT and Fe3O4 phases.
