Establishing relationship between an uniaxial pressure and an electric field shifting the Curie temperature in BaTiO${}_3$ crystals

Abstract

Shifting the Curie temperature in dependence on both uniaxial pressure and electric field in BaTiO${}_3$ crystals was studied based on literature data. It was shown that both these dependences perfectly coincide when adjusting the scale. Based on coincidence of these dependencies a relationship between both an uniaxial pressure and an electric field when shifting the Curie temperature was established.
