  • Abstract
    Magnetoelectric (ME) nanocomposite materials have attracted much interest due to the coupling among the electric, magnetic, and elastic order parameters and the ME effect, In this paper, the ¿sandwich¿ structure ME composite films of PZT/ NiFe2O4 (NFO)/PZT and PZT/CoFe2O4(CFO)/PZT were epitaxially grown on SrRuO3/STO substrates by pulsed laser deposition (PLD). The effects of strain on the microstructures, ferroelectric and magnetic properties in these thin films with few nanometer thickness have systematically been studied. The results show that the ferroelectric properties of these nanocomposite films are suppressed by inducing the magnetic layer. Compared with PZT/CFO/PZT, much improved ferroelectric properties with an out-of-plane polarization (2Pr) of 42 ¿C/cm2 and electric coercivity field of 400 kV/cm were obtained in PZT/NFO/PZT composite film.
