Electromechanical properties of lead zirconate in the vicinity of intermediate phase

Abstract

Field dependence of strain and longitudinal piezomodul as well the temperature dependence of permittivity are measured on lead zirconate ceramics in the vicinity of intermediate phase. With respect, to the intermediate phase the ferroelectric nature is proved. Large electromechanical strain and the anmalous piezoeffect allows some conclusions on the appearance and mechanism of two different field induced phase transitions. Finally it was possible to separate two mechanisms, which cause the anomalous piezoeffect.
