Abstract Ba 1−x Ce x Ti 1−y Mn y O 3 (where x and y varies from 0.00 to 0.03) ceramic samples are synthesized by conventional solid state reaction technique. The samples are sintered at 1473 K for 4 h. The grain size is observed to increase with increasing dopant and co-dopant concentration. The X-ray diffraction confirmed the cubic phase of these BaTiO 3 -based ceramics with a small amount of secondary phase. The current density shows a nearly linear relationship with voltage, and the AC resist
