“…Since its appearance and until now, nanoscale ferroics (ferromagnets, ferroelectrics, ferroelastics) have been the main object of fundamental research on the physical nature of long-range order of polar, magnetic, and structural properties [1][2][3]. The leading role is played by the emergence of a domain structure of long-range order parameters, such as electric polarization, magnetization, and (anti)ferrodistortion, and its interaction with the surface of nanoferroic [4,5]. In nanoferroics, the role of the surface increases significantly with a decrease in their size and very often begins to dominate in comparison with the bulk contribution [6].…”

Despite multiple efforts, there exist many unsolved fundamental problems related with detection and analysis of internal polarization structure and related phase transitions in ferroelectric domain walls. Their solution can be very important for the progress in domain wall nanoelectronics and related applications in advanced memories and other information technologies. Here, we theoretically study the features of phase transitions in the domain walls, which are potentially detectable by the scanning probe capacitance microwave microscopy. The finite element modelling based on the Landau-Ginzburg-Devonshire theory is performed for the capacitance changes related with the domain wall motion in a multiaxial ferroelectric BaTiO3.
