Relaxor ferroelectrics show substantial responses to electric fields. The key difference from normal ferroelectrics is a temperature-dependent inhomogeneous structure and its dynamics. The lead-based complex perovskite Pb(In1/2Nb1/2)O3 is an intrigui

An elastic anomaly at the paraelectric–ferroelectric phase transition in BaTiO3-related materials is a known precursor phenomenon. However, in the paraelectric phase, this behavior is not expected from the average crystal structure and its origin i
