Dependences of phase transitions temperatures of perovskites ABX3 (X=O or F) upon the interatomic A-X bond strains
- 1 Southern Federal University - Rostov-on-Don, Russia
Abstract
The ferro-, antiferroelectric and rotational phase transitions of known binary perovskite structure oxides (ABO3) and fluorites (ABF3) have been considered. Some correlations between their phase transition temperature values, on the one hand, and the interatomic bond А-X (X–O or F) strain values, on the other hand, have been constructed. It has been established that the known perovskite structure binary oxides and fluorites with different phase transition nature, caused of a lot of their composition and structure factors, are conditioned, among another, by the interatomic bond А-X strains in their structure.
