Critical temperature below the Curie temperature of ferroelectric ceramics PZT

Abstract

The article presents the results of research the pre-transitional features of the behavior of solid solutions based on lead zirconate-titanate. The presence of a "special"critical temperature Td on the temperature dependences of the permittivity (T) and the remanent polarization Pr(T), preceding the temperature of the paraelectric phase transition at the Curie temperature TC, is noted. In the temperature range T
