The abrupt decrease of tetragonality was induced by doping with x ≥ 0.015. Ti K-edge X-ray Absorption Near-Edge Structure (XANES) spectra indicated spontaneous polarization weakness of doped ceramics. The grain size was decreased due to the creation of oxygen vacancies and solute-drag effect. The reduction of the phase transition temperature, ferroelectricity and piezoelectricity was observed in correlation with the decrease in tetragonality. Dielectric properties near room temperature of the samples could be enhanced with Mg addition. The results here suggested that the electrical properties of this ceramic may be largely tunable by Mg dopant and could be an attractive material for high-dielectric response devices. 2018-04-25T07:03:00Z 2018-04-25T07:03:00Z 2017-06-01 Journal 23524928 2-s2.0-85019944213 10.1016/j.mtcomm.2017.05.001 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85019944213&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/46843 |
