Preparation of (Ni0.5Zn0.5)Fe2O4/Pb(Zr0.53Ti0.47)O3 thick films and their magnetic and ferroelectric properties

► NZFO/PZT multiferroic thick films with different PZT ferroelectric slurry layers are successfully prepared onto Pt/Ti/SiO2/Si substrate at low temperature of 600 °C through spin coating technique. ► Scanning electron microscope pictures suggest an optimized process of PZT slurry to film surface microstructure. ► With proper PZT slurry layer deposited, cracks can be avoided and a dense microstructure can be obtained. ► Magnetic and ferroelectric properties also reach a balance in this composition. ► A magnetoelectric coupling effect is hence predicted in this NZFO/PZT multiferroic thick film, indicating its potential application in multifunctional devices.
