Abstract: Lead-free composite thin films composed of Li 0.06K 0.47Na 0.47NbO 3 and CoFe 2O 4 were prepared using a one-step chemical method. By analysis using X-ray diffraction, thermogravimetry (TG), and differential scanning calorimetry, it was found that the Li 0.06K 0.47Na 0.47NbO 3 and CoFe 2O 4 phases were crystallized at different stages of the thermal treatment, which resulted in the formation of a composite structure. The phase segregation was confirmed by observations on scanning electron microscopy and magnetic force microscopy. By electrical and magnetic measurements it was found that the composite showed a coupled magnetoelectric behavior at room temperature with a magnetoelectric coefficient of ∼185mV/cm·Oe.
