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

TL;DR

This study demonstrates a direct relationship between uniaxial pressure and electric field in shifting the Curie temperature of BaTiO$_3$ crystals, unifying their effects through literature data analysis.

Contribution

It establishes a quantitative relationship between uniaxial pressure and electric field effects on the Curie temperature in BaTiO$_3$ crystals.

Findings

Uniaxial pressure and electric field effects on Curie temperature coincide when scaled.

A relationship linking uniaxial pressure and electric field was derived.

The study provides a unified understanding of pressure and electric field effects.

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.
