We present the results of studies in the pulsed switching of SBN crystals obtained by dielectric and optical methods. This process in SBN is characterized by a very slow kinetics even at E ≫ E c . The switched charge Q s smoothly grows with E, some

We have studied the effects of illumination by a photoactive light on the polarization switching of strontium-barium niobate crystals in quasi-static periodic electric field. The illumination results in an increase of the polarization amplitude and o

The dielectric properties of strontium-barium niobate crystals with a strontium concentration of 0.75, which corresponds to the most smeared ferroelectric phase transition, were measured. The dielectric hysteresis loops and the polarization relaxatio

Polarization and repolarization of a (100)-oriented lead magnoniobate crystal in slowly varying and dc electric fields were measured in a temperature interval including the relaxor and field-induced ferroelectric states. Throughout the interval cover

Ferroelectric relaxors lead magnesium niobate (PMN) and barium-strontium niobate (SBN) solid solutions of various compositions are shown to exhibit general features of dielectric properties in infralow frequency range. These features are related to t

It is shown experimentally in the specific example of Cr-doped barium-strontium niobate that the anomalies in the infralow-frequency dielectric properties characteristic of a ferroelectric relaxor persist over the whole temperature region of the diff

Crystalline potassium dideuterophosphate subjected to a slowly varying or a dc electric field has been found to exhibit polarization features which indicate the presence of a structural disorder characteristic of inhomogeneous systems. Continuous dis

A precision study of slow polarization in a polydomain ferroelectric has been performed on an example of triglycine sulfate samples in weak electric fields prior to and upon their γ-irradiation at doses of 0.2 and 0.3 Mrad. It is shown that in all t

Dielectric studies of the relaxation of nonequilibrium states in some polydomain ferroelectrics are presented. The domain structures in TGS and Rb2ZnCl4 crystals with rectangular and slim hysteresis loops respectively are shown to exhibit sufficientl
