Specific features of the thermal, magnetic, and dielectric properties of multiferroics BiFeO3 and Bi0.95La0.05FeO3
Abdulkarim Amirov,A. B. Batdalov,S. N. Kallaev,Z. M. Omarov,I. A. Verbenko,O. N. Razumovskaya,L. A. Reznichenko,L. A. Shilkina +7 more
TL;DR: In this paper, the properties of multiferroic BiFeO3 and Bi0.95La0.05 ceramic compounds were comprehensively studied and anomalies of the permittivity near an antiferromagnetic phase transition related to the structural variations were detected.
Journal ArticleDOI
Structural instabilities, incommensurate modulations and P and Q phases in sodium niobate in the temperature range 300 500 K
L. A. Reznichenko,L. A. Shilkina,E. S. Gagarina,I. P. Raevskii,Evgeniy Dul'kin,E. M. Kuznetsova,V. V. Akhnazarova +6 more
TL;DR: In this article, the relation between the phase transition in the vicinity of 420 K and the formation of an incommensurate phase in the temperature range 410-460 K is established based on the X-ray, dielectric, and dilatometric studies of single crystals and ceramics.
Journal ArticleDOI
Valence state of the manganese ions in mixed-valence La1−αBiβMn1+δO3±γ ceramics by Mn 2p and Mn 3s X-ray photoelectron spectra

TL;DR: In this paper, the relative valence state of Mn in La 1− α Bi β Mn 1+ δ O 3± γ (LBMO) samples and in orthorhombic manganates RMn 2 O 5 (R = Y, Bi, Eu, Gd), is studied using Mn 2p- and Mn 3s-spectra.
Journal ArticleDOI
Dielectric and Piezoelectric Properties of NaNbO3-Based Solid Solutions
L. A. Reznichenko,L. A. Shilkina,O. N. Razumovskaya,S. I. Dudkina,E. S. Gagarina,A. V. Borodin +5 more
TL;DR: In this paper, the structure and electrical properties of NaNbO3-based binary systems were analyzed and the sequences of phase changes and the stability ranges of the resulting phases were identified.
Journal ArticleDOI
Single-crystal rare earths manganites La1−x−yBixAyMnαO3±β (A = Ba, Pb): Crystal structure, composition, and Mn ions valence state. X-ray diffraction and XPS study
A.T. Kozakov,A.G. Kochur,L. A. Reznichenko,L. A. Shilkina,A. V. Pavlenko,A.V. Nikolskii,K.A. Googlev,V.G. Smotrakov +7 more
TL;DR: In this article, the relative Mn3+/Mn4+ abundance in each single crystal is determined via fitting experimental Mn2p-spectra with weighted superposition of theoretical spectra of tri-and quadrivalent Mn, and, for barium-free samples, from energy splitting of the Mn3s-Spectra components.
