摘要：

A set of the complex dielectric, piezoelectric and elastic constants of lead lanthanum zirconate titanate PLZT 9/65/35 were measured under different electric d.c. bias fields in the temperature range 77K - 380K with regard to the polarization history. The polarization was determined by the piezoelectric coefficient g and by TSDC spectra. We observed field induced ferroelectric phase transitions from a probably rhomboedral structure to an orthorhombic between 150K and 220K. If an electric bias field E greater-than-or-equal-to 3kVcm-1 is applied during cooling the rhomboedral phase is suppressed.
