Author(s): A. M. Pugachev, V. I. Kovalevskii, N. V. Surovtsev, S. Kojima, S. A. Prosandeev, I. P. Raevski, and S. I. Raevskaya Precursor dynamics of a cubic to tetragonal ferroelectric phase transition in BaTiO 3 is studied by the accurate measurement of the second harmonic generation (SHG) integral intensities. A finite signal holds for the SHG integrated intensity above the ferroelectric Curie temperature T c =403 K . Above ... [Phys. Rev. Lett. 108, 247601] Published Thu Jun 14, 2012
