Journal ArticleDOI
High energy density in silver niobate ceramics
Ye Tian,Ye Tian,Li Jin,Hangfeng Zhang,Zhuo Xu,Xiaoyong Wei,E. D. Politova,S. Yu. Stefanovich,Nadezda V. Tarakina,Isaac Abrahams,Haixue Yan +10 more
TL;DR: In this article, the average unit cell volume is seen to increase with increasing DC field and has been interpreted in terms of increasing levels of structural disorder in the system, where the structure becomes ferroelectric with high polarization.
Journal ArticleDOI
Structural and spectroscopic properties of new noncentrosymmetric self-activated borate Rb3EuB6O12 with B5O10 units
Victor V. Atuchin,Victor V. Atuchin,A.K. Subanakov,Aleksandr S. Aleksandrovsky,B. G. Bazarov,J.G. Bazarova,T.A. Gavrilova,Alexander S. Krylov,Maxim S. Molokeev,Aleksandr S. Oreshonkov,S. Yu. Stefanovich +10 more
TL;DR: In this article, a noncentrosymmetric double borate Rb3EuB6O12 was designed and synthesized by the solid state reaction method, and its crystallographic parameters were obtained by Rietveld analysis.
Journal ArticleDOI
Whitlockite solid solutions Ca9−x M x R(PO4)7 (x = 1, 1.5; M = Mg, Zn, Cd; R = Ln, Y) with antiferroelectric properties
TL;DR: In this article, the appearance of dielectric properties in whitlockites is discussed with reference to the features of their polar and centrosymmetrical structures, and the calcium-ion solid electrolyte conductivity appears either as a result of an antiferroelectric-paraelectric (AFE-PE) phase transition or as a separate phase transition near 1173 K (for x = 1.5).
Journal ArticleDOI
KTiOPO4 precipitation from potassium titanium phosphate glasses, producing second harmonic generation
Vladimir N. Sigaev,Pasquale Pernice,Antonio Aronne,O.V. Akimova,S. Yu. Stefanovich,Antonio Scaglione +5 more
TL;DR: In this paper, the same unidentified phase is formed in both these glasses and the KTP phase is only at higher temperatures, and the obtained glasses were partially opaque and phase separated.
Journal ArticleDOI
High-temperature phase transition in the whitlockite-type phosphate Ca9In(PO4)7
Vladimir A. Morozov,Vladimir A. Morozov,Alexei A. Belik,S. Yu. Stefanovich,Vadim V. Grebenev,Oleg I. Lebedev,G. Van Tendeloo,Bogdan I. Lazoryak +7 more
TL;DR: The double phosphate Ca9In(PO4)7 was obtained by solid-state reaction and was studied by room and high-temperature X-ray powder diffraction, electron diffraction and high resolution electron microscopy, differential scanning calorimetry, dielectric and conductivity measurements.
