An anomaly at 105\u2009\u00b0C was observed in dielectric and ac conductivity measurements. The activation energies for conduction (Ea) below and above this temperature are found to be 0.31 and 0.53 eV, respectively. The remanant polarization (Pr) and coercive field (Ec) at room temperature were found to be 0.64\u2002\u03bcC\/cm2 and 6.22 kV\/cm, respectively. However, a remarkable increase in these values was observed above 105\u2009\u00b0C.
