Dielectric Properties and Switching Processes of Barium Titanate⁻Barium Zirconate Ferroelectric Superlattices.

This article is devoted to the investigation of the dielectric and repolarization properties of barium zirconate and barium titanate BaZrO₃/BaTiO₃ superlattices with a period of 13.322 nm on a monocrystal magnesium oxide (MgO) substrate. Synthesized superlattices demonstrated a ferroelectric phase transition at a temperature of approximately 393 °C, which is far higher than the Curie temperature of BaTiO₃ thin films and bulk samples.
