In situ measurements of electrostrictive strain and effective dielectric constant for two ferroelectric relaxor materials, lead magnesium niobate-lead titanate (0.9PMN {center dot} 0.1PT) and lead lanthanum zirconate titanate (PLZT 9.5/65/35), were performed in the temperature ranges near their respective mean Curie points under the variation of applied electric field. The measurement results show that the polarization-related electrostrictive coefficients Q{sub y} are not constant under variation of temperature and electric field. The data also support the idea that at temperatures far above the mean Curie point, there is still a substantial amount of micropolar domain.
