Superconductor World Record Has Been Broken
2014-06-27 03:49:51

University of Cambridge A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china. The Cambridge researchers managed to 'trap' a magnetic field with a strength of 17.6 Tesla - roughly 100 times stronger than the field generated by a typical fridge magnet - in a high temperature gadolinium...

Oak Ridge National Laboratory Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors. Their work, published in Physical Review Letters, examines the role of chemical dopants, which are essential to creating high-temperature superconductors – materials that conduct electricity without resistance. The role of dopants in superconductors is...

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties – in particular, the ability to transport much more electrical current than non-engineered materials. The team includes experts from the...

Argonne National Laboratory A team of researchers from Russia, Spain, Belgium, the U.K. and the U.S. Department of Energy´s (DOE) Argonne National Laboratory announced findings last week that may represent a breakthrough in applications of superconductivity. The team discovered a way to efficiently stabilize tiny magnetic vortices that interfere with superconductivity–a problem that has plagued scientists trying to engineer real-world applications for decades. The discovery...

New images of iron-based superconductors are providing telltale clues to the origin of superconductivity in a class of ceramic materials known as pnictides. The images reveal that electrons responsible for the superconducting currents in some pnictides tend to flow primarily along the boundaries between the crystal grains that make up the superconductors. The research, which is reported in a pair of papers appearing in the current issue of the journal Physical Review B, may help physicists to...

Controlling structure on the nanoscale could lead to better superconductors Superconductors, materials in which current flows without resistance, have tantalizing applications. But even the highest-temperature superconductors require extreme cooling before the effect kicks in, so researchers want to know when and how superconductivity comes about in order to coax it into existence at room temperature. Now a team has shown that, in a copper-based superconductor, tiny areas of weak...

Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors. These findings "“ combined with iron-arsenide's potential good ability to carry current due to their low anisotropy "“ may open a door to exciting possible applications in zero-resistance power transmission.The research, led by...

Scientists from Queen Mary, University of London and the University of Fribourg (Switzerland) have found evidence that magnetism is involved in the mechanism behind high temperature superconductivity. Writing in the journal Nature Materials, Dr Alan Drew from Queen Mary's Department of Physics and his colleagues at the University of Fribourg report on the investigation of a new high temperature superconductor, the so-called oxypnictides. They found that these exhibit some striking...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
