Magnetism and Superconductivity of Transition Metal Chalcogenides

摘要

The structural, superconducting, and magnetic properties of transition metal (M) chalcogenides with layered crystal structures are considered depending on the metal-to-chalcogen (M: X) ratio. The main attention is paid to iron containing chalcogenides, in particular, to the Fe-intercalated titanium dichalcogenides FeyTiX2 and (Fe,M)(7)X-8 compounds with NiAs-type structure, and also to the materials containing a tetragonal superconducting phase of the Fe1+(Se,Te)-type.
