Estimation of Specific Heat of BaTiO₃ Crystals Derived from Relationship Between Uniaxial Pressure and Electric Field

Abstract

Shifting the Curie temperature in dependence on both uniaxial pressure and electric field in BaTiO₃ 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. The specific heat is calculated using this relationship.
