MgB2 single crystals: high pressure growth and physical properties

Physical properties of SrSn(4) single crystals.

We present detailed thermodynamic and transport measurements on single crystals of the recently discovered binary intermetallic superconductor, SrSn(4). We find this material to be a slightly anisotropic three-dimensional, strongly coupled, possibly multiband, superconductor. Hydrostatic pressure causes a decrease in the superconducting transition temperature at the rate of ≈ - 0.068 K kbar(-1)...

Growth, Characterization and Physical Properties of High−Quality Large Single Crystals of Bi2(Sr2−xLax)CuO6+δ High Temperature Superconductors

High quality large Bi2(Sr2−xLax)CuO6+δ (La-Bi2201) single crystals have been successfully grown by the traveling solvent floating zone technique. The samples are characterized by compositional and structural analyzes and their physical properties are investigated by magnetic susceptibility and resistivity measurements. Superconducting samples with sharp superconducting transitions are obtained ...

Crystal growth, structure and physical properties of crystals

Vesuvianite is an ortho-diorthosilicate of a general schematic formula X~19Y13Z18O68W10, where X – Ca and other cations, which occupy sites of coordination number 8, Y – cations occupying octahedrons and pentagonal polyhedrons: Al, Fe, Mg, Ti, etc., Z – Si in tetrahedrons, W – univalent and bivalent anions. Structures of vesuvianites are studied in dependence on a character of cation ordering i...
