And it was found that the dielectric peak isrestrained to flattened curve by bias field in samples with strong dielectricrelaxation. Debye relaxation was observed in high temperature measurements. Itis attributed to the reorientation of ionic defect dipoles formed by some pointdefects, such as oxygen vacancies. The origin of abnormal apparent dielectricconstant observed at high temperature and low frequency was discussed. Thediscussion of relationship between low temperature dielectric relaxation andpolar nanoregions involves in the containment relationship between relaxorferroelectrics and ferroelectrics with a diffused phase transition. The authorproposed that all the ferroelectrics with a diffused phase transition should berelaxor ferroelectrics or potential relaxor ferroelectrics. The only distinctionis that the frequency range where a dielectric relaxation can be observed.
