(1 - x)(Bi0.5Na0.5)TiO3/xCoFe(2)O(4) composites with x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5 were synthesized by solid state reaction method. Presence of distinct ferroelectric (Bi0.5Na0.5)TiO3 and ferrite CoFe2O4 phases in the prepared composites have been confirmed by the X-ray diffraction analysis and field emission scanning electron micrographs. The variation of dielectric constant with temperature for these prepared composites show an anomaly near antiferroelectric to paraelectric phase transition temperature (similar to 345 degrees C) of pure (Bi0.5Na0.5)TiO3 ceramics. The dielectric constant of the composites at low frequency range decreases with increase in CoFe2O4 content up to x = 0.3 but increases for x = 0.4 and x = 0.5. The value of remnant magnetization for 10 and 50% CoFe2O4 are 2 and 14 emu g(-1) respectively. The maximum value of magnetocapacitance was found to be similar to 4.37% for 50% CoFe2O4 content. Increase in CoFe2O4 content in composites shifts the optical band gap of (Bi0.5Na0.5)TiO3 towards lower energy side. (C) 2014 Elsevier B.V. All rights reserved.
