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: 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.

Аннотация: The results of a study of the transport and magnetic properties of some sulfides of 3d elements are reported. The concentration transitions with a change of conductivity type and a change of magnetic order are considered, and the features of the colossal magnetoresistance in FexMn1-xS and CuVxCr1-xS2 solid solutions are discussed.

Аннотация: New substances CuVxCr1-xS2 are synthesized in which colossal magnetoresistance (T-C = 95 K, delta(H) = -60%, H = 7 kOe), as well as the sequence of phase transitions with change in the conduction type and magnetic order, is observed as temperature is varied. The change found in the magnetic and electric properties of the CuVxCr1-xS2 compounds may be a consequence of a specific disintegration into Cu+Cr+S2 and CU2+Cr2+S2 and a change in the concentration relation between these electronic phases in the substance bulk.

Аннотация: CuCrS2 is a triangular lattice Heisenberg antiferromagnet with a rhombohedral crystal structure. We report on neutron and synchrotron powder diffraction results which reveal a monoclinic lattice distortion at the magnetic transition and verify a magnetoelastic coupling. CuCrS2 is therefore an interesting material to study the influence of magnetism on the relief of geometrical frustration.
