The study was centered on monitoring the behavior of the 1-(NbO), 1-(TiO) and 1-(MgO) stretching modes as a function of temperature. The increasing as a function of temperature for 1-(TiO) and 1-(MgO) modes, observed between 230 and 300 K, can be related to the monoclinic (MC) + tetragonal (T) phase coexistence in the PMN-PT.35-42engFerroelectricPMN-PTmonoclinic phaseArtigo10.1080/00150190802371911WOS:000260677500006Acesso restrito67259822284020548507741729691974
