Stochastic model of relaxors

Ferroelectrics, 2019
The simple stochastic model of temperature diffusing of the phase transition is presented, which takes into account the structural disorder of the material by introducing a random function – the ph...

Nanocrystalline Ferroelectric/Relaxor Multilayers

Ferroelectrics, 2002
After investigations on sputtered nanocrystalline ferroelectric Pb 0.76 Ca 0.24 TiO 3 (PTC) films and nanocrystalline relaxor films, namely Pb(Sc 0.5 Ta 0.5 )O 3 (PST), Pb(Sc 0.5 Nb 0.5 )O 3 (PSN) and Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) we started to investigate effects in multilayers of nanocrystalline ferroelectric and relaxor films.

Polar nanoclusters in relaxors

Journal of Materials Science, 2006
The central problem in the physics of relaxors is the nature of the polar nanoclusters. Whereas relaxors are homogeneous at high enough temperatures, polar nanoregions immersed in a neutral matrix are formed below a certain temperature Tb. This should lead to a two component system.

Phenomenological theory of uniaxial relaxor ferroelectrics

Journal of Physics: Condensed Matter, 2016
A phenomenological thermodynamic theory of uniaxial relaxor strontium barium niobate [Formula: see text] is developed using the Landau-Devonshire approach with two order parameters. The fourth-order thermodynamic potential allowed to explain the shape of the polarization hysteresis loops experimentally observed at different temperatures.
