摘要：
Multilayered thin films consisting of alternatively stacking Pb(Zr0.4Ti0.6)O-3 (PZT) and Ni0.8Zn0.2Fe2O4 (NZFO) layers were fabricated to exploit a strain-mediated coupling of piezoelectricity and magnetostriction. The 450-nm-thick PZT/NZFO multilayer fabricated by pulsed laser deposition showed magnetodielectric effects upon applying a static magnetic field. The magnetoelectric (ME) susceptibility values estimated using these magnetodielectric responses were in the range of 15-30 mV/cm Oe at a zero magnetic-field strength and were comparable to those obtained using a more commonly employed "dynamic" ME method.
