Abstract
The formation and development of bulk crystallochemical defects-mesoscopic clusters representing the nuclei of new phases-was studied in systems exhib iting concentration phase transitions. When a solid solution approaches a m orphotropic region, the clusters exhibit a stepwise evolution involving sev eral stages manifested by corresponding changes in macroscopic properties. The role of clusters in the development of the extreme electrophysical prop erties of the objects studied is discussed. (C) 2000 MAIK "Nauka/Interperio dica".
