Piezoelectric hysteresis and relaxation processes in ferroelectric ceramics in weak electric fields
Year: 2024
Type: article
Abstract: The processes of piezoelectric relaxation and hysteresis in ferroelectric piezoelectric ceramics based on the lead zirconate-titanate system are studied in the region of weak electric fields. An analysis of the field and time dependences of the complex piezoelectric modulus |d31| obtained by processing sequentially measured piezoresonance spectra of the radial vibration mode of thin piezoceramic disks using the piezoresonance spectrum analysis method and program (PRAP) was carried out. A physical interpretation of the results obtained is proposed.
