Showing papers on "High-temperature superconductivity published in 1985"
TL;DR: In this article, it was shown that the recently found superconducting state below 6 K in β-(BEDT-TTF)2I3 under a pressure of 1.5 kbar is diamagnetic and exhibits Meissner effects of up to 24 %, indicating that superconductivity is a true volume effect in these crystals.

TL;DR: In this article, the assumption that the net gain in energy is equivalent to the repulsive electron-ion and electron-electron Darwin interactions, an expression for Tc has been obtained which depends on only a few atomic parameters.
Abstract: Based on the assumption that in the groundbcs state the net gain in energy is equivalent to the repulsive electron-ion and electron-electron Darwin interactions, an expression forTc has been obtained which depends on only a few atomic parameters. The theory provides a criterion for the occurrence of superconductivity and yields satisfactory values ofTc for metals and alloys, and ternary chalcogenides and borides. It explains the difference inTc in the crystalline and amorphous states as well as the pressure dependence ofTc. The possibility of occurrence of high temperature superconductivity has been explored.

TL;DR: In this article, total energy-local density calculations were performed to explore the possibility of forming the Bl-phase by subjecting the preferred hexagonal (δ) phase to hydrostatic pressure.
Abstract: Recent predictions based on electronic structure calculations and empirical evidence indicate that MoN would be a very high temperature superconductor if it could be formed in the rock salt structure. We report results on total energy-local density calculations which explore the possibility of forming the Bl-phase by subjecting the preferred hexagonal (δ) phase to hydrostatic pressure.

TL;DR: A surface superconductivity can occur in ferromagnets because of the branching domains near the surface as mentioned in this paper, which accounts for the experimental evidence of superconductivities in the normal ferromagnetic phase of recoverable superconductors.

TL;DR: In this paper, it was shown that intermetallic compounds with transition metal components from the second long period and/or a nontransition element component from the first long period have a higher superconductivity temperature than analogous compounds having corresponding components from other periods of the periodic table.
