A conversion was facilitated with magneto-electric effect between energies stored in ferromagnetic form and piezoelectric one in material. This paper is concerned with magneto-electric performance of composites with a bi-layered structure for ceramic (Na0.5K0.45Li0.05)(Nb0.9Ta0.08Sb0.02)O3, i.e., KNN, and metal nickel. Lead-free piezoelectric KNN ceramics were synthesized by the two-step sintering process. More than 96% of theoretical density for the ceramics was obtained, and, the d33 of the KNN sample was about 300pC/N. Based on the high piezoelectric performance of the KNN ceramic, a lead-free magneto-electric composite was prepared by gluing KNN ceramic with Ni plate together. The magneto-electric effect of the bi-layered composites with various thickness ratios was investigated in details, with a magneto-electric coefficient of about 10mV/Oe.
