Ferroelectric and Ferromagnetic Behavior of Pb(Zr_(0.52)Ti_(0.48))O_3-Co_(0.9)Zn_(0.1)Fe_2O_4 Multilayered Thin Films Prepared via Solution Processing

摘要

Multilayered multiferroic nanocomposite films of Pb(Zr_(0.52)Ti_(0.48))O_3 (PZT) and Co_(0.9)Zn_(0.1)Fe_2O_4 (CZFO) are prepared on general Pt/Ti/SiCVSi substrates via a simple solution-processing method. Structural characterization by X-ray diffraction and electron microscopy techniques reveals good surface and cross-sectional morphologies of these multilayered thin films. In particular, at room temperature strong ferroelectric and ferromagnetic responses are simultaneously observed in the multilayered thin films, depending on the deposited sequences and volume fractions of ferroelectric PZT phase and magnetic CZFO phase.
