Journal ArticleDOI
Measurement of piezoelectric constants of lanthanum-gallium tantalate crystal by X-ray diffraction methods
TL;DR: In this paper, a method for measuring piezoelectric constants of crystals of intermediate systems by X-ray quasi-multiple-wave diffraction is proposed and implemented, which makes it possible to determine the piezolectric coefficient by measuring variations in the lattice parameter under an external electric field.
Journal ArticleDOI
Formation of Unusual Nonferroic Domains in TeO 2 Single Crystals under External Electric Field
TL;DR: In this article, the formation of unusual slowly relaxing domains under an external dc electric field has been revealed in paratellurite (TeO2) crystals, characterized by the existence of a threshold field strength (at which domains begin to be formed) and long equilibrium settling times (up to a few hours, depending on the electric field strength).
Journal ArticleDOI
Bimorph Actuator: a New Instrument for Time-Resolved X-ray Diffraction and Spectroscopy
A. E. Blagov,A. E. Blagov,A. G. Kulikov,A. G. Kulikov,N. V. Marchenkov,N. V. Marchenkov,Yury Pisarevsky,Yury Pisarevsky,M. V. Kovalchuk,M. V. Kovalchuk +9 more
TL;DR: In this paper, a vibrating bimorph actuator based on a bidomain bending-type crystal of lithium niobate has been used for time-resolved X-ray experiments at both laboratory X-Ray sources and synchrotron facilities.
Journal ArticleDOI
Laboratory time-resolved X-ray diffractometry for investigation of reversible structural changes induced in single crystals by external electric field
N. V. Marchenkov,A. G. Kulikov,A. G. Kulikov,Arsen Petrenko,Arsen Petrenko,Yu. V. Pisarevsky,Yu. V. Pisarevsky,A. E. Blagov,A. E. Blagov +8 more
TL;DR: The absence of the diffraction curve broadening effect was shown as well as the other significant relaxation-like variations of the curve parameters which are inherent for the migration of charge carriers (ions or vacancies) under the external electric field.
Journal ArticleDOI
LiNbO3-based bimorph piezoactuator for fast X-ray experiments: Static and quasistatic modes
A. G. Kulikov,A. G. Kulikov,A. E. Blagov,A. E. Blagov,N. V. Marchenkov,N. V. Marchenkov,A. V. Targonsky,A. V. Targonsky,Ya. A. Eliovich,Ya. A. Eliovich,Yu. V. Pisarevsky,Yu. V. Pisarevsky,Mikhail V. Kovalchuk,Mikhail V. Kovalchuk +13 more
TL;DR: In this paper, a new adaptive bending X-Ray optics (ABXO) element for fast X-ray beam parameters control is investigated and described, which operates on a bending oscillation principle and consists of LiNbO3 based bimorph piezoactuator and a silicon single crystal of high quality mounted on its edge.
