Abstract

90BiFeO3–10BaTiO3 (90BFO–10BT) multiferroic material was synthesized by a Sol-Gel method. We have reported microstructure with the enhanced dielectric properties of multiferroic mixed-perovskite 90BFO–10BT compound by scanning electron microscopy (SEM) and conventional dielectric measurements. XRD observations showed secondary phase appearance during synthesis because of instability of Bismuth and charge fluctuation of Fe. Dielectric behavior of the 90BFO–10BT ceramics were studied at various temperature and frequency. It was also found that doping of BiFeO3 by insulating BaTiO3 enhanced the dielectric properties. The dielectric constant was found to be very high (εr′ = 102, for T = 140°C). The Maxwell–Wagner type relaxation in the sample results a considerably high dielectric constant in 90BFO–10BT ceramics.
