Ferroelectric domain pattern in barium titanate single crystals studied by means of digital holographic microscopy

Original language description

It is known that the appearance of ferroelectric domain patterns plays an essential role in many physical phenomena (such as ferroelectric phase transitions, ferroelectric switching, etc.), which are important in the application of ferroelectric materials. At the same time, experimental techniques, which allow fast real-time observations of domain patterns in the whole volume of the ferroelectric crystal, are not widely available. In this Article, we report on the real-time observation of the ferroelectric domain pattern in the single crystal of barium titanate by means of digital holographic microscopy (DHM). The principles of DHM observations of domain patterns in perovskite single crystals are reviewed. A modification of the DHM technique, which allows a fast and accurate determination of important geometric parameters of the ferroelectric domain patterns (such as domain spacing or the volume fraction of the anti-parallel domains) is presented. Our particular implementation of DHM is based on Mach-Zehnder interferometer and the numerical processing of data employs the angular spectrum method. In addition to the earlier DHM studies of domain patterns in lithium niobate and lithium tantalate, our results indicate that the DHM is a convenient method to study a dynamic evolution of ferroelectric domain patterns in all perovskite single crystals.
