Beznosikov, B. V.
Crystal chemistry and structure of expected compounds A2BX4. II. Oxides, selenides, and sulfides 061A2B6+X4 2- and 080A2 2+B4+X4 2-. / B. V. Beznosikov, K. S. Aleksandrov // Sov. Phys.: Crystallogr. - 1985. - Vol. 30, Is. 5. - P. 533-535 ; Crystallography Reports ; Kristallografiya
Аннотация: Predictions of A2BX4 compounds for compositions 071A2 +B6+X4 2- with type structures of K2MgF4, beta -K2SO4, spinel, olivine, thenardite, phenacite, Sr2PbO4, and Pb3O4 are presented. K2MgF4 type structures are known and probable only in oxides and sulphides with hexavalent uranium because their formation is limited by the size of the hexavalent B cation. Structures of the beta -K2SO4 type are stable in compounds with large A cations. Among the sulphides with 076A2 +B6+X4 2-, the spinel crystal structure is as yet unknown, but is most probable in compounds with A+ = Li, Na, Ag, and with B6+ = Mo, W, and U. The olivine type structure is known only in Ag2CrO4, and no new compounds with this structure are expected to be found. A phenacite structure is probable only in three new oxides and in some sulphides with Li as A+. A thenardite type structure is probable in oxides with B6+ = Fe and Mn, but sulphides are unlikely. For 076A2 2+B4+X4 2- compounds with large A2+ ions and B4+ ions with radii from 0.57 A to RB 0.48RA + 0.11, a K2MgF4 structure would exist. For even larger A ions, the Sr2PbO4 structure would exist. In oxides with cations A2+ = Pb and Sn, compounds with Pb3O4 type structures are probable.-D.F.P.

    Переход металл-диэлектрик в катион-замещенных соединениях ReхMn1-xS (Re = Gd, Sm, Ho) / О. Б. Романова [и др.] // Вестник СибГАУ. - 2015. - Т. 16, № 2. - С. 478-484. - Библиогр.: 38. - Работа выполнена при финансовой поддержке РФФИ № 15-42-04099 р_Cибирь_а и государственного задания № 114090470016. . - ISSN 1816-9724
   Перевод заглавия: Metal-insulator transition in the cation-substituted compounds RexMn1-xS (Re = Gd, Sm, Ho)
Кл.слова (ненормированные):
СУЛЬФИДЫ РЕДКОЗЕМЕЛЬНЫХ ЭЛЕМЕНТОВ -- ПРОВОДИМОСТЬ -- ПЕРЕХОД МЕТАЛЛ-ДИЭЛЕКТРИК -- ТЕРМОЭДС -- SULFIDES OF RARE-EARTH ELEMENTS -- CONDUCTIVITY -- TRANSITION METAL-INSULATOR -- THERMOELECTRIC POWER
Аннотация: Представлены результаты исследования транспортных свойств катион-замещенных сульфидов RexMn1-xS (Re = Gd, Sm, Ho) с ГЦК-решеткой типа NaCl в области температур 77-1200 К. С увеличением степени катионного замещения в этих соединениях RexMn1-xS (Re = Gd, Sm, Ho) изменяется тип проводимости от полупроводникового до металлического при критической концентрации Х С. Концентрационный переход металл-диэлектрик в системе Gd XMn 1-XS сопровождается уменьшением величины удельного электросопротивления на 12 порядков и коэффициента термоЭДС (α) на два порядка. Катионное замещение в твердых растворах GdxMn1-xS приводит к смене дырочного типа проводимости (α > 0), свойственного моносульфиду марганца, на электронный (α < 0). Уменьшение величины α с увеличением содержания гадолиния в решетке MnS указывает на то, что Gd действует как донорная примесь. Для Sm 0,2Mn 0,8S обнаружен резкий максимум сопротивления при Т = 100 К, который может быть вызван рассеянием электронов проводимости на спиновых флуктуациях локализованных электронов. Установлен металлический тип проводимости для Sm 0,25Mn 0,75S и механизм электрического сопротивления, который связан с рассеянием электронов на акустических фононах и с магнитным рассеянием на нескомпенсированных антиферромагнитных кластерах марганца при Т < 180 К. В результате замещения марганца самарием в твердом растворе SmxMn1-xS электронная структура перестраивается, и сопротивление невозможно объяснить на основе протекания ионов самария. Общей закономерностью температурных зависимостей коэффициента термоЭДС как для системы с гадолинием, так и для системы с самарием является проявление отрицательного значения термоЭДС во всем диапазоне температур с ростом Х. В системе HoxMn1-xS переход металл-диэлектрик обнаружен для ХС = 0,3 с уменьшением величины удельного электросопротивления на десять порядков. Цель данной работы - установить условия реализации перехода металл-диэлектрик в катион-замещенных системах RexMn1-xS (Re = Gd, Sm, Ho).
This paper presents the results of a study of the transport properties of cation-substituted sulfides Re XMn 1-XS (Re = = Gd, Sm, Ho) with FCC NaCl type in the temperature range 77-1200 K. With increasing degree of cation substitution in these compounds Re XMn 1- ХS (Re = Gd, Sm, Ho) the conductivity type changes from the semiconductor to the «metal» at the critical concentration X C. The concentration of metal-insulator transition in the system Gd XMn 1-XS is accompanied by a decreasing in the electrical resistivity of value on 12 orders and Seebeck coefficient (α) is on two orders. The cation-substitution in the solid solutions Gd XMn 1-XS leads to p-type conductivity (α > 0), as comprising to electronic (α < 0) for manganese monosulfide. Decrease of α with increasing gadolinium concentration in the MnS lattice indicates that the Gd acts as a donor impurity. For Sm 0,2Mn0,8S a maximum resistance at T = 100 K attributed to the scattering of conduction electrons by spin fluctuations of localized electrons. The metallic conductivity for Sm 0.25Mn 0.75S and the mechanism of electrical resistance, which is related to the scattering of electrons by acoustic phonons and magnetic scattering by uncompensated antiferromagnetic manganese clusters at T < 180 K were revealed. As a result of the substitution of manganese to samarium in solid solution Sm XMn 1-XS the electron structure is reconstructed, and the resistance cannot be explained on the basis of the percolation of samarium ions. The temperature dependence of Seebeck coefficient for systems with gadolinium and with samarium reveals the negative values of thermoelectric power in the all range of temperatures with increasing concentration (X). The metal-insulator transition for system Ho XMn 1-XS at Х С= 0,3 is observed with decreasing resistivity on ten orders. The purpose of this work is to establish conditions for the realization of the metal-insulator transition in a cation-substituted systems Re XMn 1-XS (Re = Gd, Sm, Ho).

Аннотация: Variable-valence TmxMn1–xS (0 ⩽ x ⩽ 0.15) compounds have been synthesized and their structural, electrical, and thermoelectrical properties have been studied in the temperature range of 80–1100 K. The regions of existence of solid solutions of sulfides TmxMn1–xS with the NaCl-type fcc lattice have been determined. It has been found that, as thulium ions are substituted for manganese cations, the electrical resistivity increases, and the lattice parameter increases more sharply than that corresponding to the Vegard’s law. The study of the temperature dependences of the thermopower coefficient has revealed that the current carrier sign is retained to 500 K for all the substitution concentrations, and the charge carrier type changes from the hole type to the electron type with variations in the temperature. The experimental data have been explained in terms of the exciton model.

Аннотация: Regions of the existence of sulfide Gd (x) Mn1 - x S and selenide Ti (x) Mn1 - x Se solid solutions have been identified. Their electrical and thermoelectric properties have been studied in the temperature range 80-900 K. It has been established that the substitution of Gd2+ and Ti2+ ions for Mn2+ cations initiates reversal of the type of charge carrier with respect to the starting compounds MnS and MnSe. The cation substitution in solid solutions brings about a change from the hole conduction (alpha 0) characteristic of the manganese monosulfide and monoselenide to the electronic conduction (alpha 0).

Аннотация: We have studied the resistivity and thermoelectromotive force (thermo emf) in a temperature range of T = 80-1000 K, the magnetic susceptibility and magnetization in a temperature range of T= 4.2-300 K at an external magnetic field of up to 70 kOe, and the structural characteristics of CoxMn1 - S-x sulfides (0 <= x <= 0.4). Anomalies in the transport properties of these compounds have been found in the temperature intervals Delta T-1 = 200-270 K and Delta T-2 = 530-670 K and at T-3 similar to T-N. The temperature dependences of the magnetic susceptibility, magnetization, and resistivity, as well as the current-voltage characteristics, exhibit hysteresis. In the domain of magnetic ordering at temperatures below the Neel temperature (TN), the anti ferromagnetic CoxMn1 - xS sulfides possess a spontaneous magnetic moment that is explained using a model of the orbital ordering of electrons in the t(2g) bands. The influence of the cobalt-ion-induced charge ordering on the transport and magnetic properties of sulfides has been studied. The calculated values of the temperatures corresponding to the maxima of charge susceptibility, which are related to a competition between the on-site Coulomb interaction of holes in various subbands and their weak hybridization, agree well with the experimental data.

Аннотация: Results of an experimental study of MnS, FeS, and FexMn1-xS single crystals are presented. The phase composition, the lattice parameters, and the state of paramagnetic ions in FexMn1-xS have been determined by x-ray diffraction analysis and Mossbauer spectroscopy. A sequence of transitions have been found in iron manganese sulfide with x = 0.29 at temperatures T-1 approximate to 25-50 K, T-2 approximate to 125 K, and T-3 approximate to 190 K with a change in kinetic properties and the formation of a metallic state at low temperatures T approximate to 2 K. The possibility of a Mott-Hubbard transition in FexMn1-xS sulfides with variation of the composition and the temperature is discussed.

Magnetic properties of FexMn1-xS sulfides exhibiting the magnetoresistive effect / G. A. Petrakovskii [et al.] // Phys. Solid State. - 2002. - Vol. 44, Is. 10. - P. 1925-1928, DOI 10.1134/1.1514782. - Cited References: 10 . - ISSN 1063-7834

Аннотация: The magnetic, electrical, and thermal (derived from DTA data) properties of FexMn1 - xS polycrystalline sulfides (0less than or equal toxless than or equal to0.38) synthesized based on alpha-MnS (NaCl cubic lattice) and exhibiting colossal magnetoresistance were studied. The studies were conducted at temperatures from 77 to 1000 K and magnetic fields of up to 30 kOe. As the degree of cation substitution in the FexMn1 - xS system was increased, the magnetic order was found to change from antiferromagnetic to ferromagnetic. In the high-temperature domain (550-850 K), the samples undergo two phase transitions with critical temperatures T-c1 and T-c2, which are accompanied by reversible anomalies in the magnetization and thermal (DTA) properties and by a semiconductor-metal transition.
