Journal ArticleDOI
The negative phonon confinement effect in nanoscopic sodium nitrite
E. Yu. Koroleva,Dmitry Nuzhnyy,Jan Pokorny,S. Kamba,Yu. A. Kumzerov,Sergey Vakhrushev,Jan Petzelt +6 more
TL;DR: A nanocomposite of porous glass and a NaNO(2) ferroelectric was studied using infrared reflectivity, THz transmission and Raman spectroscopy, indicating that the stiffening of the effective modes is due to local depolarization fields on the glass-ferroelectric interfaces.
Journal ArticleDOI
Structural Peculiarities of the Intermediate Phase in Zr-Rich Lead Zirconate Titanate
Daria Andronikova,I. A. Bronwald,I. A. Bronwald,N. G. Leontyev,I. N. Leontyev,D. Yu. Chernyshov,A. V. Filimonov,Sergey Vakhrushev +7 more
TL;DR: In this paper, the results of X-ray diffraction studies on a single crystal of lead zirconate titanate PbZr0.993Ti0.007O3 in the region of existence of an intermediate ferroelectric phase were presented.
Journal ArticleDOI
Neutron diffraction study of the (BiFeO3)1-x(PbTiO3)x solid solution: nanostructured multiferroic system.
I. V. Golosovsky,Sergey Vakhrushev,José Luis García-Muñoz,Michela Brunelli,W. M. Zhu,Zuo-Guang Ye,Vassil Skumryev +6 more
TL;DR: In this paper, the authors performed neutron diffraction studies on the solid solution of (BiFeO(3))(1-x)(PbTiO(4)+ ions in the two phases and revealed a mixture of two nanoscale phases with different crystal structures.
Journal ArticleDOI
Structure of disordered lead indoniobate PbIn1/2Nb1/2O3
Journal ArticleDOI
Inelastic and Quasielastic Neutron Scattering in PbMg1/3Nb2/3O3 Above the Burns Temperature
R. G. Burkovsky,Sergey Vakhrushev,Stephen M. Shapiro,A. Ivanov,Kazuma Hirota,Masato Matsuura +5 more
TL;DR: The results of the study of the true paraelectric phase of PMN via neutron inelastic and quasielastic scattering in two different Brillouin zones were treated simultaneously in terms of the 2-mode approach for the lowest TO mode.
