Real-time study of domain dynamics in ferroelectric Sr0.61Ba0.39Nb2O6
TL;DR: In this paper, the ferroelectric domain reversal of strontium barium niobate (Sr0.61Ba0.4Nb2O6 or SBN:61) single crystals by electric-field poling using liquid electrodes is reported.

Beam fanning reversal in the ferroelectic relaxor Sr0.61Ba0.39Nb2O6 at high external electric fields
TL;DR: In this article, the photorefractive response in SBN strongly depends on the state of the polar structure of the crystal, which can be controlled by external electric fields, and the model of scattering centers associated with refractive index anomalies located on domain walls is applied to receive detailed information about the distribution of initial seed scattering in the crystal bulk and the efficiency of nonlinear amplification of the scattering.

Optical recording of reversed domains in a Ce-doped SBN:75 crystal for bit-oriented three-dimensional optical memory
TL;DR: In this article, a bit-oriented three-dimensional recording with a Ce-doped Sr0.75Ba0.25Nb2O6 (SBN:75) crystal was developed.

Optical and electrical Barkhausen noise induced by recording ferroelectric domain holograms
TL;DR: In this paper, the Barkhausen noise in current and diffraction efficiency was measured while optically recording domain gratings and showed that the two are strongly correlated in time and significant random depolarization occurs under high-intensity illumination.
