Elastic and anelastic properties of poled and depoled single crystals of Pb(In₁/₂Nb₁/₂)O₃-Pb(Mg₁/₃Nb₂/₃)O₃-PbTiO₃ with compositions close to the morphotropic boundary have been investigated over the temperature range 5–700 K by resonant ultrasound spectroscopy (RUS) at frequencies of 0.1–1.2 MHz. Steep elastic softening occurs in a temperature interval of at least 250 K as the Vogel-Fulcher freezing interval and cubic → tetragonal transition point, T c, are approached from above. This is...[Show more]
