Anisotropic precursor behavior in LiTaO3: Polar coherence at ultrahigh temperatures without ferroelasticity
We report the persistence of the converse piezoelectric effect to exceptionally high temperatures in ferroelectric congruent LiTaO3 single crystals. Resonant piezoelectric spectroscopy reveals a strong and stable piezoelectric response up to temperatures approaching the ferroelectric transition (Tc = 855 K), demonstrat...
