“…The depolarization field produced by the bound charges leads to the appearance of nanodomains at the boundary and their growth into the virgin material. Such mechanism has been discussed for relaxor ferroelectrics to explain formation of a nanodomain structure after heating of a single-domain crystal from a ferroelectric to a relaxor phase, consisting of isolated nonpolar regions within a ferroelectric matrix [ 22 , 23 ].…”

Ferroelectric nanodomains were formed in bulk lithium niobate single crystals near nanostructured microtracks laser-inscribed by 1030-nm 0.3-ps ultrashort laser pulses at variable pulse energies in sub- and weakly filamentary laser nanopatterning regimes. The microtracks and related nanodomains were characterized by optical, scanning probe and confocal second-harmonic generation microscopy methods. The nanoscale material sub-structure in the microtracks was visualized in the sample cross-sections by atomic force microscopy (AFM), appearing weakly birefringent in polarimetric microscope images. The piezoresponce force microscopy (PFM) revealed sub-100 nm ferroelectric domains formed in the vicinity of the embedded microtrack seeds, indicating a promising opportunity to arrange nanodomains in the bulk ferroelectric crystal in on-demand positions. These findings open a new modality in direct laser writing technology, which is related to nanoscale writing of ferroelectric nanodomains and prospective three-dimensional micro-electrooptical and nanophotonic devices in nonlinear-optical ferroelectrics.

“…Recently, Goldring et al [10] investigated the optical properties of PLZT (9.5/65/35) for use in ultrafast electro-optic switches and found non-linearities in the observed birefringence caused by temperature and frequency variations, as well as elapsed time. Several other recent papers [11,12] have concentrated on studying the dielectric properties of various relaxor PLZT ceramics in order to better understand their paraelectric-ferroelectric phase transition and domain dynamics arising from changes in La-content, temperature and applied electric fields. The dielectric properties are essential features to study since they are a direct measurement of dipole moments, and can provide explanations for any electro-optic or strain anomalies and non-linearities exhibited by the material.…”

The change in the transverse refractive indices of clamped transparent relaxor ferroelectric PLZT ceramics, having a composition of (9.5/65/35) and (9.0/65/35), were measured as a function of various ac and dc electric fields, as well as frequency and elapsed time, using an interferometric technique. It was found that the refractive index changed only in the same direction of the applied field, and that increasing dc fields decreased this refractive index, while increasing ac fields increased it, especially in composition (9.5/65/35). These results were explained on the basis of movement and creation of domain structures.
