The dielectric constant and hysteresis loops for the non--fatigued sample were measured and compared with those for the fatigued sample at room temperature and with those for the fatigued sample annealed above the Curie temperature for hours. The experimental results show that the temperature dependences of dielectric constant and the hysteresis loops of the fatigued sample annealed above the Curie temperature for hours differ significantly from those of the non--fatigued sample.The SEM analysis indicates that the facture mode is mainly trans--granular for the non—fatigued sample, while inter--granular for the fatigue sample. The magnitude of strain due to the 90.domain reorientation during the application of an AC electric field, estimated from the in--situ XRD spectra, reaches as high as 0.1%. This repeated and high strain induced by the 90 domain reorientations ultimately leads to electric fatigue of the samples.
