Abstract: Multiferroic nanocomposite films composed of P(VDF-TrFE) copolymer and CoFe₂O₄ (CFO) nanoparticles have been prepared by a modified polymeric processing. Structural characterizations reveal that CFO nanoparticles with 80–100 nm diameters are well distributed in the P(VDF-TrFE) matrix. The crystalline and microstructure of P(VDF-TrFE) are strongly dependent on the volume fraction of CFO nanoparticles, which are further analyzed by Raman spectra. Consequently, the ferroelectric and magnetoelectric responses are strongly influenced by the concentration of CFO nanoparticles. A significant magnetoelectric coupling effect of around 40 mV/cm  Oe is obtained from the nanocomposites. A relatively simple model has been adopted to calculate the magnetoelectric coefficient, which is also in agreement with the experimental results.
