Resistivity Switch Plays Role Of Magnetism In Iron-based Superconductors
2013-06-06 13:31:12

Ames Laboratory Physicists at the U.S. Department of Energy´s Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings, reported in Nature Communications, offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors. “We found that the directions of smallest and largest resistivity within the conducting layers are significantly dependent on the composition...

Measuring Magnetic Fingerprints Of Superfluid Helium-3

Physikalisch-Technische Bundesanstalt Superconducting sensors of PTB allow highly sensitive measurements of the nuclear magnetic resonance of thin helium-3 layers With their SQUIDs, low-temperature specialists of the Physikalisch-Technische Bundesanstalt (PTB) have made it possible for the magnetic moments of atoms of the rare isotope 3He (helium-3) to be measured with extreme sensitivity. With the aid of these sensors, highly sensitive nuclear resonance spectrometers were developed...

Helmholtz Association of German Research Centres In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled. The objective of their...

To engineers, it´s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current. “The story of electrical conduction in metals is told entirely in terms of electrons.  The cuprates show that there is something completely new to be understood beyond...

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...

Findings explain unusual properties, but complicate search for universal theory Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously promising idea for new types of zero-resistance electronics and energy-storage and transmission systems. At present, a key step to achieving superconductivity (in addition to keeping the...

Vortex Pinning May Lead To Breakthroughs In Superconducting

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
