Phenomenological theory of phase transitions in epitaxial BaTiO3 thin films
V. B. Shirokov, Yu. I. Yuzyuk, B. Dkhil +1
We develop a phenomenological thermodynamic theory of ferroelectric BaTiO3 (BT) thin films epitaxially grown on cubic substrates using the Landau-Devonshire eight-order potential.…

Comparative study of phase transitions in polycrystalline and epitaxial BaTiO3 thin films by means of specific heat measurements
B. Strukov, S. Davitadze, V. Lemanov +3
The experimental data on the thermal properties of the nanostructured perovskite ferroelectrics are presented and analysed. The ability of the modified 3w method for specific heat…

Clarification of size effects in polycrystalline BaTiO3 thin films by means of the specific heat measurements: grain size or film thickness?
B. A. Strukov, S. T. Davitadze, S. G. Shulman +2
Specific heat of polycrystalline BaTiO3 thin films on the fused quartz substrate was measured by ac-hot probe method. Phase transition temperature, excess entropy and spontaneous p…
