Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding"”and ultimately controlling"”this effect remains a challenge, because much about manganite physics is still not known. A research team lead by Maria Baldini from Stanford University and Carnegie...

A team of physicists has taken a big step toward the development of useful graphene spintronic devices. The physicists, from the City University of Hong Kong and the University of Science and Technology of China, present their findings in the American Institute of Physics' Applied Physics Letters. Graphene, a two-dimensional crystalline form of carbon, is being touted as a sort of "Holy Grail" of materials. It boasts properties such as a breaking strength 200 times greater than steel and, of...

Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been published in the...

SAN JOSE, Calif., Dec. 23, 2010 /PRNewswire/ -- Highlights: IBM Research is the first to measure the movement and processing of digital data as a magnetic pattern on nanowires 1,000 times finer than a human hair. New memory uses the spin of electrons to move data at hundreds of miles per hour to atomically precise positions along the nanowire racetrack. This memory could someday enable a single portable device to store all the movies produced worldwide in a given year and run on a...

With the help of neutrons, TUM physicists discover new ways to save data One of the requirements to keep trends in computer technology on track "“ to be ever faster, smaller, and more energy-efficient "“ is faster writing and processing of data. In the Dec. 17 issue of the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the Universitaet zu Koeln report results that could point the way to a solution. TUM physicists set a lattice of magnetic vortices in...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
