Complex sulfides -- Crystal structure -- SEM -- Raman
Аннотация: Ternary sulfides BaPrCuS3 and BaSmCuS3 are first synthesized by the sulphidation reaction of a mixture of related oxides and metal Cu in a flow of (CS2, H2S) at 1170 K. The crystal structures of BaPrCuS3 and BaSmCuS3 are obtained by Rietveld method. BaPrCuS3 crystallizes in space group Pnma with unit cell parameters a = 10.56074(6), b = 4.11305(2) and c = 13.42845(7) Å, V = 583.289 (5) Å3, Z = 2 (structure type Eu2CuS3). BaSmCuS3 crystallizes in space group Cmcm with unit cell parameters a = 4.07269(4), b = 13.4499(1) and c = 10.3704(1) Å, V = 568.06 (1) Å3, Z = 2 (structure type KZrCuS3). The structural model is proposed for the Cmcm→Pnma transition in ABCX3 (X = S, Se) compounds for the sequence Sm-Pm-Nd-Pr. The dimensionless tolerance factor t = IR(A) × IR(C)/IR(B)2 is suggested to control the boundary between the Cmcm and Pnma structures. The micromorphological, thermal and spectroscopic properties are evaluated for BaPrCuS3. The compound melts incongruently at Tmelt = 1580.9 K. In BaPrCuS3, the band gap is estimated to be 2.1 eV. The vibrational parameters of BaPrCuS3 and BaSmCuS3 are comparatively observed by Raman spectroscopy.

Sulfur-rich fluid -- Iron carbide -- Diamond -- Mantle sulfides -- High-pressure experiment
Аннотация: Experimental study, dedicated to understanding the effect of S-rich reduced fluids on the diamond-forming processes under subduction settings, was performed using a multi-anvil high-pressure split-sphere apparatus in Fe3C-(Mg,Ca)CO3-S and Fe0-(Mg,Ca)CO3-S systems at the pressure of 6.3 GPa, temperatures in the range of 900–1600 °C and run time of 18–60 h. At the temperatures of 900 and 1000 °C in the carbide-carbonate-sulfur system, extraction of carbon from cohenite through the interaction with S-rich reduced fluid, as well as C0-producing redox reactions of carbonate with carbide were realized. As a result, graphite formation in assemblage with magnesiowüstite, cohenite and pyrrhotite (±aragonite) was established. At higher temperatures (≥1100 °C) formation of assemblage of Fe3+-magnesiowüstite and graphite was accompanied by generation of fO2-contrasting melts - metal-sulfide with dissolved carbon (Fe-S-C) and sulfide-oxide (Fe-S-O). In the temperature range of 1400–1600 °C spontaneous diamond nucleation was found to occur via redox interactions of carbide or iron with carbonate. It was established, that interactions of Fe-S-C and Fe-S-O melts as well as of Fe-S-C melt and magnesiowüstite, were С0-forming processes, accompanied by disproportionation of Fe. These resulted in the crystallization of Fe3+-magnesiowüstite+graphite assemblage and growth of diamond. We show that a participation of sulfur in subduction-related elemental carbon-forming processes results in sharp decrease of partial melting temperatures (~300 °C), reducting the reactivity of the Fe-S-C melt relatively to FeC melt with respect to graphite and diamond crystallization and decrease of diamond growth rate.

Аннотация: The permittivity of TmxMn1–xS (0 < x < 0.15) solid solutions is measured in the frequency range of 102–106 Hz at temperatures of 300–500 K in magnetic fields of up to 12 kOe. The migration and relaxation conductivity contributions to the electric polarization are established. The relaxation time and activation energy are calculated using the Debye model. A decrease in the capacitance and relaxation time in a magnetic field is observed. The electron polarization relaxation channel provided by recombination of the electron–hole pairs is found using the infrared spectroscopy investigations.

Аннотация: New multifunction materials in the AgXMn1‒XS (Х = 0.05) system have been synthesized and investigated in the temperature range of 77‒500 K in magnetic fields up to 12 kOe. Near the temperature of the magnetic transition (ТN = 176 K), the anomalous behavior of the temperature dependence of magnetization has been observed and has been attributed to the formation of ferrons. An analysis of the infrared spectroscopy data and I‒V characteristics has revealed the spin-polaron subband splitting. Several conductivity channels have been found from the impedance spectra. The temperature and magnetic field dependences of the carrier relaxation time have been obtained. The magnetoresistance (−21%), magnetoimpedance (−65%), magnetothermopower (−40%), and photoconductivity effects have been detected. The majority carrier type, density, and mobility have been determined from the Hall-effect measurement data. The observed effects have been explained using a ferron model.
Синтезированы и исследованы новые многофункциональные материалы системы AgXMn1-XS (Х=0.05) в интервале температур 77-500К в магнитных полях до 12 кЭ. В близи температуры магнитного перехода (ТN=176К) наблюдается аномальное поведение температурной зависимости намагниченности, вызванное образованием ферронов. Найдено расщепление спин-поляронной подзоны из ИК спектроскопии и вольт-амперных характеристик. Установлено несколько каналов проводимости из спектров импеданса, отличающихся частоте. Определена зависимость времени релаксации носителей заряда от температуры и магнитного поля. Обнаружено четыре эффекта: магнитосопротивление (-21%), магнитоимпеданс (-65%), магнитотермоЭДС (-40%) и фотопроводимость. Найдены: тип, концентрация и подвижность основных носителей заряда из холловских измерений. Обнаруженные эффекты объясняются в модели ферронов.

Аннотация: The series of iron sulfide nanoparticles (NPs) were synthesized with the polyol mediated process which exploits high-boiling polyalcohol solvents at different boiling temperatures (TB) what determined the NPs phase state from Fe3S4 to FeS. The XRD and HRTEM revealed the content of the Fe3S4 cubic phase to reduce linearly with the TB increase, and at TB=320 ˚C the FeS phase became predominant. Non monotonous coercivity dependence on the NPs phase state is revealed and interpreted.
Серия наночастиц (NPs) сульфидов железа синтезирована с помощью полиольного метода, в котором используются высокотемпературные растворы полиспиртов при различных температурах (TB), что определяет фазовый состав NPs от Fe3S4 до FeS. XRD и HRTEM показали, что содержание кубической фазы Fe3S4 в NPs линейно уменьшается при увеличении TB и при TB=320˚C гексагональная фаза FeS становится преобладающей. Обнаружена и объяснена немонотонная зависимость коэрцитивной силы NPs от их фазового состава.

Iron carbide -- Graphite -- Diamond -- Sulfur-rich fluid -- Mantle sulfides -- High-pressure experiment
Аннотация: Experimental modeling of natural carbide-involving reactions, implicated in the graphite and diamond formation and estimation of the iron carbide stability in the presence of S-bearing fluids, sulfide melts as well as mantle silicates and oxides, was performed using a multi-anvil high-pressure split-sphere apparatus. Experiments were carried out in the carbide-sulfur (Fe3C-S), carbide-sulfur-oxide (Fe3C-S-SiO2-MgO) and carbide-sulfide (Fe3C-FeS2) systems, at pressure of 6.3 GPa, temperatures in the range of 900–1600 °C and run time of 18–40 h. During the interaction of cohenite with S-rich reduced fluid or pyrite at 900–1100 °C, extraction of carbon from carbide was realized, resulting in the formation of graphite in assemblage with pyrrhotite and cohenite. At higher temperatures complete reaction of cohenite with newly-formed sulfide melt was found to produce metal-sulfide melt with dissolved carbon (Fe64S27C9 (1200 °C)–Fe54S40C6 (1500 °C), at.%), which acted as a crystallization medium for graphite (1200–1600 °C) and diamond growth on seeds (1300–1600 °C). Reactions of cohenite and oxides with S-rich reduced fluid resulted in the formation of graphite in assemblage with highly ferrous orthopyroxene and pyrrhotite (900–1100 °C) or in hypersthene formation, as well as graphite crystallization and diamond growth on seeds in the Fe-S-C melt (1200–1600 °C). We show that the main processes of carbide interaction with S-rich fluid or sulfide melt are recrystallization of cohenite (900–1100 °C), extraction of carbon and iron in the sulfide melt, and graphite formation and diamond growth in the metal-sulfide melt with dissolved carbon. Our results evidence that iron carbide can act as carbon source in the processes of natural graphite and diamond formation under reduced mantle conditions. We experimentally demonstrate that cohenite in natural environments can be partially consumed in the reactions with mantle silicates and oxides, and is absolutely unstable in the presence of S-bearing reduced fluid or sulfide melt at temperatures higher than 1100 °C, under lithospheric mantle pressures.

Аннотация: We report on the novel heterometallic quaternary sulfides SrLnCuS3 (Ln = La, Nd, Tm), obtained as both single crystals and powdered samples. The structures of both the single crystal and powdered samples of SrLaCuS3 and SrNdCuS3 belong to the orthorhombic space group Pnma but are of different structural types, while both samples of SrTmCuS3 crystallize in the orthorhombic space group Cmcm with the structural type KZrCuS3. Three-dimensional crystal structures of SrLaCuS3 and SrNdCuS3 are formed from the (Sr/Ln)S7 capped trigonal prisms and CuS4 tetrahedra. In SrLaCuS3, alternating 2D layers are stacked, while the main backbone of the structure of SrNdCuS3 is a polymeric 3D framework [(Sr/Ln)S7]n, strengthened by 1D polymeric chains (CuS4)n with 1D channels, filled by the other Sr2+/Ln3+ cations, which, in turn, form 1D dimeric ribbons. A 3D crystal structure of SrTmCuS3 is constructed from the SrS6 trigonal prisms, TmS6 octahedra and CuS4 tetrahedra. The latter two polyhedra are packed together into 2D layers, which are separated by 1D chains (SrS6)n and 1D free channels. In both crystal structures of SrLaCuS3 obtained in this work, the crystallographic positions of strontium and lanthanum were partially mixed, while only in the structure of SrNdCuS3, solved from the powder X-ray diffraction data, were the crystallographic positions of strontium and neodymium partially mixed. Band gaps of SrLnCuS3 (Ln = La, Nd, Tm) were found to be 1.86, 1.94 and 2.57 eV, respectively. Both SrNdCuS3 and SrTmCuS3 were found to be paramagnetic at 20-300 K, with the experimental magnetic characteristics being in good agreement with the corresponding calculated parameters.
