Inexpensive Magnetic Field Sensor From 'Plastic Paint'
2012-06-12 12:38:48

Spintronic device uses thin-film organic semiconductor University of Utah physicists developed an inexpensive, highly accurate magnetic field sensor for scientific and possibly consumer uses based on a "spintronic" organic thin-film semiconductor that basically is "plastic paint." The new kind of magnetic-resonance magnetometer also resists heat and degradation, works at room temperature and never needs to be calibrated, physicists Christoph Boehme, Will Baker and colleagues report...

Physicists from the University of Bonn split an atom using quantum mechanics precision Researchers from the University of Bonn have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allow dividing atoms - similarly to light rays - and reuniting them. The researchers want to build quantum mechanics bridges by letting the atom touch adjacent atoms while it...

Excitons form Bose-Einstein condensate Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will allow scientists to better study the physical properties of excitons, which exist only fleetingly yet offer promising applications as diverse as efficient harvesting of solar energy and ultrafast computing. "The realization of the exciton condensate in a trap opens the opportunity to study...

Berkeley Lab researchers and their colleagues demonstrate unique new materials for innovative electronic and magnetic applications Strange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. First theorized and then discovered by researchers at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues in other institutions, these “strong 3-D topological...

Findings support magnetic pairing theory that could lead to new improved superconductors By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Cornell University, St. Andrews University, and collaborators provide direct evidence supporting theories in which magnetism holds the key to this material's ability to carry current with no resistance. Because...

Minute-scale interactions govern electronic behavior of superconductors with potential applications for voltage measurement techniques Researchers studying a superconducting strip observed an intermittent motion of magnetic flux which carries vortices inside the regularly spaced weak conducting regions carved into the superconducting material. These vortices resulted in alternating static phases with zero voltage and dynamic phases, which are characterized by non-zero voltage peaks in the...

Physicists show standard ℠quasiparticle´ theory breaks down at ℠quantum critical point´ A new study this week finds that “quantum critical points” in exotic electronic materials can act much like polarizing “hot button issues” in an election. Reporting in Nature, researchers from Rice University, two Max Planck Institutes in Dresden, Germany, and UCLA find that on either side of a quantum critical point, electrons fall into line and behave as...

Long predicted but never observed, coherent quantum phase slip can be harnessed to develop a novel class of quantum devices A new type of quantum bit called a "phase-slip qubit", devised by researchers at the RIKEN Advanced Science Institute and their collaborators, has enabled the world's first-ever experimental demonstration of coherent quantum phase slip (CQPS). The groundbreaking result sheds light on an elusive phenomenon whose existence, a natural outcome of the hundred-year-old...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
