Journal ArticleDOI
Phase transitions and soft modes in sodium bismuth titanate
Sergey Vakhrushev,V. A. Isupov,B. E. Kvyatkovsky,N. M. Okuneva,I. P. Pronin,G. A. Smolensky,P. P. Syrnikov +6 more
TL;DR: In this article, the results of experimental studies of the crystal and domain structures of NaO, 5BiO and 5TiO3 as well as its lattice dynamics, dielectric, optical and other physical properties are considered.
Journal ArticleDOI
Long-time relaxation of the dielectric response in lead magnoniobate
TL;DR: It is shown that the dielectric permittivity of a single crystal lead magnoniobate in the zero- field zero-fieldcooled regime depends linearly on both the inverse temperature and the inverse applied field strength.
Journal ArticleDOI

Alexander K. Tagantsev,Kaushik Vaideeswaran,Sergey Vakhrushev,Alexey Filimonov,R. G. Burkovsky,R. G. Burkovsky,A. P. Shaganov,Daria Andronikova,A. I. Rudskoy,Alfred Q. R. Baron,Hiroshi Uchiyama,Dmitry Chernyshov,Alexei Bosak,Z. Ujma,Krystian Roleder,Andrzej Majchrowski,Jae-Hyeon Ko,Nava Setter +17 more
TL;DR: This work reports the results of a study on the lattice dynamics of the antiferroelectric lead zirconate using inelastic and diffuse X-ray scattering techniques and the Brillouin light scattering, and suggests an approach to the treatment of complex phase transitions in ferroics.
Journal ArticleDOI
Local and long range polar order in the relaxor-ferroelectric compounds PbMg 1 / 3 Nb 2 / 3 O 3 and PbMg 0.3 Nb 0.6 Ti 0.1 O 3
Brahim Dkhil,Jean Michel Kiat,Jean Michel Kiat,Gilbert Calvarin,Gianguido Baldinozzi,Sergey Vakhrushev,Emmanuelle Suard +6 more
TL;DR: In this paper, the structural evolution of PMN/PT10% and PMN (PbMg 0. 3 Nb 0. 6 Ti 0. 1 O 3 ) was studied and compared using high-resolution x-ray and neutron diffraction.
Journal ArticleDOI
Glassy phenomena in disordered perovskite-like crystals
TL;DR: In this paper, the wavevector dependence of this diffuse scattering has been well described by Ornstein-Zernice formula and correlation length temperature dependence resembling that of spin-glasses has obtained.
