Abstract

Properties of BaTiO₃ nanoparticles, transition into the ferroand paraelectric BaTiO₃ phase, and dependence of Curie temperature T_c(BaTiO₃) on the energy of excited states of a Ba atom are studied in the terms of the nanoparticle shell theory. Dimensional properties of ferroelectric BaTiO₃ and PbTiO₃ nanoparticles are compared.
