On the possible internal structure of the ferroelectric Ising lines in BaTiO3
This article is devoted to a detailed analysis of the inner structure of the Ising line, a topological defect separating two parts of a ferroelectric Bloch domain wall with opposite helicity, in the framework of the phenomenological Ginzburg...

Domain walls of BaTiO3 and PbTiO3 within Ginzburg-Landau-Devonshire model
It is argued that the ratio of the 90-degree and 180-degree domain wall widths is primarily determined by the polarization gradient term, which happens to be strongly anisotropic in the BaTiO3 case....

Ferroelectric domain walls and their intersections in phase-field simulations
This chapter deals with phenomenological theoretical description of ferroelectric domain walls in perovskite ferroelectrics in the framework of Ginzburg-Landau-Devonshire theory. Its first part focuses mostly on the Bloch-l...

Ising lines: natural topological defects within ferroelectric Bloch walls
Phase-field simulations demonstrate that the polarization order-parameter field in the Ginzburg-Landau-Devonshire model of rhombohedral ferroelectric BaTiO3 allows for an interesting linear defect, stable under sim...
