Abstract: A multilayer heterostructure composite thin films consisting of alternating layers (Pb 0.76Ca 0.24)TiO 3 (PCT) and CoFe 2O 4 (CFO) were grown on Pt/Ti/SiO 2/Si(100) substrate by a sol-gel process. X-ray measurements indicated high quality of crystallization of both PCT and CFO layers. The magnetic and ferroelectric properties of the composite were investigated. Well-defined polarization vs. electric field (P-E) and magnetic hysteresis (M-H) loops were obtained. A strong magnetoelectric (ME) response was observed in the sample which was subjected to an alternating magnetic field, and a high ME voltage coefficient α E = 870 mV/Oe cm was obtained for the composite thin films when applied magnetic field parallel to the sample plane.
