Ni0.23Fe2.77O4 (NFO)/Pb(Zr,Ti)O3 (PZT) multiferroic composites were synthesized by spin-spray deposition of NFO film onto PZT at 90 °C. Strong interface adhesion between NFO and PZT was observed, which was verified by high resolution transmission electron microscopy indicating excellent wetting between the NFO and PZT, and by the strong magnetoelectric coupling in the NFO/PZT multiferroic composite showing an electric field induced remnant magnetization change of 10%. This strong interface adhesion and low-temperature spin-spray synthesis of multiferroic materials provide an alternative route for novel integrated multiferroic materials and devices.
