Publisher's Synopsis
Written both for experimentalists and theorists, this book provides a theoretical basis for the interpretation of data on the influence of defects on the properties of ferroelectrics and related materials. The authors use a general theoretical approach to discuss such questions as the origin and properties of the bias field, influence of defects on the anomalies of thermodynamic quantities and kinetic coefficient light scattering phenomena. General questions such as the percolation of ordering, glass state, and nonergodic behaviour are discussed, along with the smearing of phase transitions important in applications.
