Position Sensors: Magnets Know Their Place
February 29, 2008 — Non-contact position sensors are small but important parts of many modern machines. Researchers have used a phenomenon known as magnetoresistance to develop a practical, low-cost position sensor that ... > full story -
Switchyard For Single Electrons
February 25, 2008 — Scientists have transferred very small charge "packets," comprising a well-defined number of few electrons, between metallic electrons precisely by using a single-electron pump. A single-electron ... > full story -
Experiment Tightens Limits On Dark Matter: Physicists Revive Bubble Chamber Technology To Search For WIMPs
February 14, 2008 — Scientists working on the COUPP experiment at DOE's Fermilab have announced a new development in the quest to observe dark matter. The experiment tightened constraints on "spin-dependent" properties ... > full story -
Graphene Holds Promise For Spintronics
February 10, 2008 — Graphene is a nanomaterial combining very simple atomic structure with intriguingly complex and largely unexplored physics. Since its first isolation about four years ago researchers suggested a ... > full story -
Magnetism Loses Under Pressure
January 29, 2008 — Scientists discovered that the magnetic strength of magnetite -- the most abundant magnetic mineral on Earth -- declines drastically when put under pressure. Researchers have found that when ... > full story -
Earth's Getting 'Soft' In The Middle, Geologists Note
January 24, 2008 — A new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly, suggesting that the material there is softer than ... > full story -
Physicists Find New Explanation For Superconductivity's 'Glue'
December 20, 2007 — Researchers have identified an alternative explanation for the microscopic origins of the "glue" that binds electrons during high-temperature ... > full story -
Pure Spin Currents In Silicon Generated, Modulated, And Electrically Detected
December 3, 2007 — Scientists have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. This demonstration is a key ... > full story -
Blue Dye Could Hold The Key To Super Processing Power
November 28, 2007 — A technique for controlling the magnetic properties of a commonly used blue dye could revolutionize computer processing power, according to new research. Scientists have demonstrated that they can ... > full story -
Optical Technique For Controlling Electron Spins In Quantum Dot Ensembles Developed
November 15, 2007 — Scientists are closer to developing novel devices for optics-based quantum computing and quantum information processing, as a result of a breakthrough in understanding how to make all the spins in an ... > full story
