Abstract
Composite (x)CoFe2O4-(1 â x)BaTiO3 thick films were prepared on alumina substrate by electrophoretic deposition technique using CoFe2O4 and BaTiO3 nanopowders. X-ray diffraction indicated that the films consisted of both spinel CoFe2O4 and perovskite BaTiO3 phase. Microstructures of the deposited films were examined using SEM technique. Electrical and dielectric properties of the thick films were investigated. At CoFe2O4 concentration of 55%, the composite thick film showed an abrupt rise in dc conductivity, which was attributed to percolation effect.
