superconductors new insulator material
2014/9/12
Research from North Carolina State University shows that a type of modified titania, or titanium dioxide, holds promise as an electrical insulator for superconducting magnets, allowing heat to dissipa...
Limitations on the Ginzburg criterion for dirty superconductors
dirty superconductors Ginzburg criterion superconducting fluctuations specific heat
2012/2/27
The contributions of superconducting fluctuations to the specific heat of dirty superconductors are calculated, including quantum and classical corrections to the `usual' leading Gaussian divergence. ...
Organic superconductors with an incommensurate anion structure
organic superconductor incommensurate composite crystal Fermi surface
2010/1/19
Superconducting incommensurate organic composite crystals based on the methylenedithio-tetraselenafulvalene (MDT-TSF) series donors, where the energy band filling deviates from the usual 3/4-filled, a...
Chemistry of layered d-metal pnictide oxides and their potential as candidates for new superconductors
layered d-metal pnictide oxides potential new superconductors
2010/1/19
The description of the two types of layers in our article is inaccurate. All the [M2Pn2] and [M2Ch2] (M = d-metal; Pn = pnictogen; Ch = chalcogen) layers, which were described as 'fluorite-type', cons...
Chemistry of layered d-metal pnictide oxides and their potential as candidates for new superconductors
low-dimensional compound structure-property relationship suboxide CDW (charge-density wave) SDW (spin-density wave)
2010/10/12
Layered d-metal pnictide oxides are a unique class of compounds which consist of
characteristic d-metal pnictide layers and metal oxide layers. More than 100 of these layered
compounds, including th...
The basic formulae of London theory for superconductors are reviewed. Moreover, an expression for the spatial charge density in a type-II superconductor is obtained; this equation is associated with s...
High-Temperature Superconductors and Related Compounds Studied by Mössbauer Spectroscopy
High-Temperature Superconductors Mö ssbauer Spectroscopy
2010/12/15
57Fe, 119Sn, and 151Eu Mössbauer spectroscopy was used to study the chemical structure, phonon mode changes, and low-temperature phase transformation around the Tc as well as suppression of super...
Magnetic flux can penetrate a type-II superconductor in the form of flux-lines or Abrikosov vortices, each of which carry a quantum of flux and arrange in a more or less regular triangular lattice. Un...
