Аннотация: The electrical characteristics including the electrical resistance, impedance, I–V characteristics, capacitance, dissipation factor, and thermoelectric power of the Bi2Sn2-хFeхO7 (х = 0.1, 0.2) stannates have been investigated in the temperature range of 100–600 K at frequencies of 102–106 Hz. The paramagnetic contribution of electrons to the dynamic magnetic susceptibility has been established. The conductivity mechanism of the compounds has been found from the I–V characteristics and the change in the carrier sign has been determined from the thermoelectric power. The hysteresis of the I–V curves, charge transfer currents and polarization current have been observed in the Bi2Sn1·8Fe0·2O7 compound. A nonlinear field dependence of the polarization in the orthorhombic phase has been found. The correlation between the obtained characteristics and the phase structure transitions has been established. Two relaxation channels and activation energy have been found using the Debye model. The hysteretic I–V characteristics have been explained using a model of the electronic structure and the dipole and migration polarization.

Аннотация: The magnetic and magnetodielectric properties of bismuth pyrostannate Bi2(Sn1-xFex)2O7 (x= 0.1 and 0.2) have been examined. Using the Mossbauer spectroscopy and electron paramagnetic resonance, the high-spin state and crystallographic positions of iron ions have been established.

Заглавие : Study of structural properties of bismuth pyrostannate by Raman and IR spectroscopy
Место публикации : Sib. J. Sci. Technol. - 2020. - Vol. 21, Is. 4. - P.556-564. - ISSN 2587-6066, DOI 10.31772/2587-6066-2020-21-4-556-564; \b Сибирский журнал науки и технологий

Аннотация: Chromium-substituted bismuth pyrostannates with a pyrochlore structure were synthesized by the solid-phase reaction method. The X-ray structural analysis performed at room temperature showed that the samples Bi2(Sn1-xCrx)2O7, x = 0; 0.05, 0.1 are single-phase and belong to the Pc monoclinic structure. Polymorphic transformations of the synthesized samples were studied by Raman and IR spectroscopy. IR spectra were obtained at the temperature range 110–525 K and frequencies 350–1100 cm–1. Raman spectra were measured at room temperature at frequencies of 100–3000 cm–1. Heterovalent substitution of Sn4+ for Cr3+ modifies the spectra of pure Bi2Sn2O7. The crystal structure of Bi2Sn2O7 consists of two oxygen sublattices: SnO6 and Bi2O'. Chromium ions substituted tin ions in the SnO6 oxygen octahedra, distorting the local structure in the vicinity of bismuth ions. Phonon modes are softening in the vicinity of phase transitions. А shift of the phase boundaries of polymorphic transitions is observed for Bi2(Sn1-хCrх)2O7, x = 0.05, 0.1. The frequencies of stretching vibration modes were determined from IR and Raman spectra. The substitution of chromium for tin ions resulted in the appearance of two new modes at frequencies of 581 and 822 cm–1 in the Raman spectra. The absence of an inversion center in the crystal structure of Bi2(Sn1-xCrx)2O7 is confirmed by Raman spectroscopy. IR spectra of chromium-substituted samples consist of complex lines, which decompose into 2 and 3 Lorentzian lines. The softening and broadening of optical absorption modes are associated with the electronic contribution. Impurity states of electrons form polarons.Методом твердофазной реакции синтезированы хромзамещенные пиростаннаты висмута со структурой пирохлора. Рентгеноструктурный анализ, выполненный при комнатной температуре, показал, что образцы Bi2(Sn1-хCrх)2O7, х = 0; 0,05, 0,1 однофазные и принадлежит к моноклинной структуре Pc. Полиморфные превращения синтезированных образцов изучались методами Раман и ИК спектроскопии. ИК-спектры получены в температурном диапазоне 110-525 К, интервале частот 350-1100 см-1. Спектры Рамановского рассеяния измерялись при комнатной температуре на частотах 100-3000 см-1. Гетеровалентное замещение Sn4+ на Cr3+ видоизменяет спектры чистого Bi2Sn2O7. Кристаллическая структура Bi2Sn2O7 состоит из двух кислородных подрешеток: SnO6 и Bi2O′. Ионы хрома замещают ионы олова в кислородных октаэдрах SnO6, искажая локальную структуру в окрестности ионов висмута. Вблизи фазовых переходов происходит смягчение фононных мод. Для Bi2(Sn1-хCrх)2O7, 0,05, 0,1 наблюдается смещение фазовых границ полиморфных переходов. Из ИК и Раман спектров определены частоты мод валентных колебаний. В Рамановских спектрах замещение ионов олова хромом привело к появлению двух новых мод на частотах 581 и 822 см-1. Отсутствие центра инверсии в кристаллической структуре Bi2(Sn1-хCrх)2O7 подтверждается Раман спектроскопией. ИК спектры хромзамещенных образцов состоят из сложных линий, которые разлагаются на 2 и 3 линии Лоренцовой формы. Смягчение и уширение спектров поглощения связывается с электронным вкладом. Примесные состояния электронов образуют поляроны.

Аннотация: The Nd1Bi2Fe5O12/Nd2Bi1Fe4Ga1O12 polycrystalline films on the glass substrate and the Nd0.5Bi2.5Fe5O12 epitaxial films on the single-crystal gadolinium gallium garnet substrate have been investigated by impedance and dielectric spectroscopy. The inductive contribution to the impedance and two relaxation channels related to ferroelectric domains and migration polarization have been established. The magnetocapacitance and magnetoimpedance have been determined. The conductive and polarization currents and the phase difference between them for the films of two types have been determined. The critical temperatures of the polarization disappearance and hysteresis I–V have been found. A model of the polarization caused by the piezoelectric effect and flexoelectric interaction has been proposed. I–V hysteresis is explained by the presence of ferroelectric domains near the interface and is associated with the hysteresis of the electric polarization.

Аннотация: Bismuth ferrite films have been synthesized by the burst-mode deposition of the BiFe0.8Co0.2O3 solid solutions onto object glasses. The surface morphology of the BiFe0.8Co0.2O3 films has been examined. The effect of electron doping implemented by substitution of cobalt for iron in the BiFe0.8Co0.2O3 films on their magnetic, electrical, and galvanomagnetic properties has been investigated at temperatures of 77-600 K in magnetic fields of up to 12 kOe. The negative magnetoresistance has been observed, which changes its sign in the region of formation of magnetically heterogeneous states and attain its maximum value above room temperature. It has been established that the magnetoresistance is caused by the competition of electron hoppings and localization of electrons in a magnetic field. Using the Hall measurements, the carrier type has been determined. A model of the change in the curriers sign upon heating due to the shift of the chemical potential relative to the impurity subband has been proposed.

Аннотация: The photoinduced diode effect has been found in BiMnxFe1-xO3 (0 X 0.15) films in the near-infrared and violet spectral ranges in a wide temperature interval. The dependences of the diode effect on temperature, wavelength, and illumination power have been established. The mechanism of the ferroelectric diode has been determined using its I-V characteristics at different illumination powers, optical spectra, far-infrared absorption spectra, and electric polarization hysteresis. The interplay between the photodiode effect and conductivity mechanism has been elucidated. The model of strong Coulomb potential fluctuations and quantum well asymmetry caused by the electric polarization in the film and difference between the times of carrier thermalization and recombination of electrons and holes is proposed.В пленках феррита висмута BiMnxFe1-xO3 (0 x 0.15) обнаружен фотоиндуцированный диодный эффект в ближней инфракрасной и фиолетовой областях спектра в широкой области температур. Определена зависимость диодного эффекта от температуры, длины волны, мощности освещения. Механизм ферроэлектрического диода определяется из вольт-амперных характеристик при разных интенсивностях освещения, оптических спектров и спектров поглощения в дальней ИК области, гистерезиса электрической поляризации. Устанавливается связь фотодиодного эффекта с механизмом проводимости. Предложена модель сильных флуктуаций кулоновского потенциала, асимметрия квантовых ям в результате наличия электрической поляризации в пленке и отличие времен термолизации носителей тока и рекомбинации электронов и дырок.

Аннотация: Film structures in the Fe-Bi system have been studied experimentally. The magnetic state of the two-layer structures is shown by electron magnetic resonance to be dependent on the order of depositing magnetic and nonmagnetic layers. The three-layer structures demonstrate the effect of the exchange bias, the value of which is dependent on the bismuth interlayer thickness.

Заглавие : Effect of a Substrate on the Magnetoelectric Effect in Rare-Earth-Doped Bismuth Iron Garnet
Место публикации : JETP Letters. - 2019. - Vol. 110, Is. 3. - P.223-230. - ISSN 00213640 (ISSN), DOI 10.1134/S0021364019150074
Примечания : Cited References: 29. - This work was supported jointly by the Russian Foundation for Basic Research, the Government of the Krasnoyarsk Territory, and the Krasnoyarsk Science Foundation (project no. 18-42-240001 “Temperature-Induced Reversal of the Sign of Magnetoelectric Tensor Components in Neodymium-Doped Bismuth Iron Garnet”), as well as in part by the Russian Foundation for Basic Research (project nos. 18-32-00079_mol_a and 18-52-00009_bel_a) and by the Russian Ministry of Science and Higher Education (state contract no. 3.5743.2017/6.7).
Аннотация: The mechanism of relaxation of the electric polarization in thin films of rare-earth-doped bismuth iron garnet on glass and gallium gadolinium garnet substrates is determined in magnetic fields of 0 and 12 kOe in the temperature range of 80–380 K. The change in the sign of the residual electric polarization after switching off the electric field and the magnetic-field-induced shift of the hysteresis loop in the applied magnetic field are found. Linear and quadratic magnetoelectric effects with the tensor components depending on the substrate type are observed. The linear magnetoelectric effect is related to the spin–orbit coupling of electrons at the film–substrate interface, whereas the quadratic one is determined by the exchange–striction mechanism.

Аннотация: Apatite Pb3Bi2(GeO4)3 was obtained by the solid-phase method from the initial oxides of PbO, Bi2O3 and GeO2 by sequential firing in air at temperatures of 773–1003 K. Its crystal structure has been refined by X-ray diffraction. The high-temperature heat capacity (350–1000 K) of this compound was measured by differential scanning calorimetry. Based on these data, the main thermodynamic functions are calculated.
