UPTON, NY—A team of scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Columbia Engineering, Columbia Physics and Kyoto University has discovered an unusual form of ...
7-Mar-2007，DENVER, CO Although it was discovered more than 20 years ago, a particular type of high-temperature (Tc) superconductor ?material that conducts electricity with almost zero resistance ?is r...
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...
