Multiferroic 2-2 type bi-layered NFO/(Pb{sub 0.80}Sr{sub 0.20}) TiO{sub 3} composite thin film on Pt/TiO{sub 2}/Si substrate was prepared by novel metallo-Organic process using spin coating technique. The structural and surface morphology were confirmed by X-Ray diffraction (XRD) atomic force microscope (AFM). Significantly improved ferroelectric properties (P{sub s} ~ 17.25, P{sub r} ~ 8.02 µC/cm{sup 2} and E{sub c} ~ 404 kV/cm) and magnetic properties (M{sub s} ~ 117 emu/cc, M{sub r} ~ 0.83 emu/cc and H{sub c} ~ 20 Oe) were observed at room temperature. The leakage current densities in NFO/PST composites film have been studied. Poole–Frankel bulk limited conduction mechanism dominates of film at relatively high electric filed.
