“…Temperature dependence of the electrical conductivity was measured by a DC four-probe method in the temperature range between 2 and 300 K. The sintered sample was cut into a piece whose size was approximately 5 × 1.5 × 1.5 mm 3 . To connect four wires to the sample, a silver paste was used.…”

A ternary metal-rich telluride Pd2NiTe2 has been prepared by the solid-state reaction. This compound crystallizes in the orthorhombic K2ZnO2-type structure with space group Ibam. In this structure, the Ni atom is tetrahedrally coordinated and the NiTe4 tetrahedra share edges forming one-dimensional chains with short Ni-Ni bondings along the c-axis. Through magnetic susceptibility, specific heat, and electrical resistivity measurements, this compound shows Pauli paramagnetism and metallic electrical conductivity. The electronic structure calculation of Pd2NiTe2 suggests that its electrical conductivity is a three-dimensional one, which is caused by conduction bands originated from d orbitals of Pd and Ni and p orbitals of Te.

“…It is well known that superconductors are classified as type-I superconductors for κ < 1/ √ 2 and type-II superconductors for κ > 1/ √ 2. CuRh 2 S 4 is a typical type-II superconductor with κ P =0 = 21 ÷ 38 [2]. The increasing value of κ/κ P =0 means that the characteristics of the type-II superconductor of this system are further enhanced by pressurization.…”

We investigated the magnetic properties of chalcogenide-spinel superconductor CuRh2S4 under pressure and estimated the pressure dependence of the superconducting parameters. With increasing pressure, the superconducting transition temperature (Tc), thermodynamic critical field (Hc), upper critical field (Hc2), penetration depth (λ), and GL parameter (κ) increase. Meanwhile, the lower critical field (Hc1) is unchanged and the Ginzburg-Landau coherence length (ξGL) is reduced by pressurization. The increasing value of κ indicates enhanced characteristics of the type-II superconductor CuRh2S4.

Replacement reactions ('pseudomorphism') commonly occur in Nature under a large range of conditions (T 25 to >600 ˚C; P 1 to >5 kbar). Whilst mineral replacement reactions are often assumed to proceed by solid-state diffusion of the metal ions through the mineral, many actually proceed via a coupled dissolution and reprecipitation (CDR) mechanism. In such cases, a starting mineral is dissolved into a fluid and this dissolution is coupled with the precipitation of a replacement phase across the reaction front. In cases where there are close relationships between the crystal structures of the parent and newly formed minerals, the replacement can be topotactic (interface-coupled dissolution and reprecipitation). The kinetics and chemistry of the CDR route are fundamentally different from solid-state diffusion and can be exploited i) for the synthesis of materials that are often difficult to synthesise via traditional methods and ii) to obtain materials with unique properties. This review highlights recent research into the use of CDR for such synthetic challenges. Emphasis has been given to i) the use of CDR to synthesise compounds with relatively low thermal stability such as the thiospinel mineral violarite ((Ni,Fe) 3 S 4 ), ii) preliminary work into use of CDR for the production of roquesite (CuInS 2 ), a potentially important photovoltaic component and, iii) examples where the textures resulting from CDR reactions are controlled by the nature and texture of the parent phase and the reaction conditions; these being the formation of micro-porous gold and three-dimensional ordered arrays of nanozeolite of uniform size and crystallographic orientation.
