Role of Domain Walls on Macroscopic Properties of Perovskite Ceramics
Original language description
It is known that the both dielectric and piezoelectric properties of polydomain perovskite ceramics and single crystals are to a large extent influenced by the presence of domain walls. For that reason, the effects of domain phenomena on the dielectric and piezoelectric properties of perovskite ferroelectrics have been comprehensively investigated for several decades. Many experimental observations of nonlinear polarization and strain responses to the applied electric field match the so-called Rayleighlaw. It indicates that macroscopic properties of the material are influenced by the domain wall motions, which are controlled by the interaction of the domain walls with crystal lattice defects. On the other hand, several observations of strong piezoelectric response of domain engineered samples, where the driving force for the domain wall movement was absent, has been reported recently. Such experimental results indicated the existence of different physical phenomena which control the m
