Phenomenological theory of phase transitions in epitaxial BaxSr(1-x)TiO3 thin films
V. B. Shirokov, Yu. I. Yuzyuk, B. Dkhil +1
A phenomenological thermodynamic theory of BaxSr(1-x)TiO3 (BST-x) thin films epitaxially grown on cubic substrates is developed using the Landau-Devonshire approach. The eighth-ord…
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…
Concentration phase diagram of Ba(x)Sr(1-x)TiO3 solid solutions
V. B. Shirokov, V. I. Torgashev, A. A. Bakirov +1
Method of derivation of phenomenological thermodynamic potential of solid solutions is proposed in which the interaction of the order parameters of constituents is introduced throu…
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…
Landau Level Quantization and Possible Superconducting Instabilities in Highly Oriented Pyrolitic Graphite
Y. Kopelevich, V. V. Lemanov, S. Moehlecke +1
Measurements of the basal-plane resistivity rho_a(T,H) performed on highly oriented pyrolitic graphite, with magnetic field H parallel to the c-axis in the temperature interval 2 -…
