Device controls electron spin at room temperature
In a breakthrough for applied physics, North Carolina State University researchers have developed a magnetic semiconductor memory device, using GaMnN thin films, which utilizes both the charge and spin of electrons at room temperature.   view more (2009-04-07)

Letting the spin loose
Two properties of an electron-its spin and its charge-are generally thought to be inseparable, intrinsic characteristics, no more given to sudden changes or going off on their own than say, the fur on a cat or the paint on a bicycle. But a team of scientists at the Weizmann Institute of Science has recently demonstrated conclusively that, in very... view more... (2005-07-13)

UBC researchers put a new spin on electrons
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.   view more (2009-04-16)

Discovery by UC Riverside physicists could enable development of faster computers
Physicists at UC Riverside have made an accidental discovery in the lab that has potential to change how information in computers can be transported or stored. Dependent on the "spin" of electrons, a property electrons possess that makes them behave like tiny magnets, the discovery could help in the development of spin-based... view more... (2008-06-24)

Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or instead of their charge. One thing spinning... view more... (2007-02-16)

Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits.   view more (2009-01-16)

Technology May Cool The Laptop
Does your laptop sometimes get so hot that it can almost be used to fry eggs?   view more (2009-10-30)

Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means... view more... (2009-01-22)

Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies.   view more (2008-05-28)

Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of the external magnetic field. This exciting new... view more... (2002-08-15)

Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields.   view more (2007-11-02)

Plenty of nothing: A hole new quantum spin
Electronic devices are always shrinking in size but it's hard to imagine anything beating what researchers at the University of New South Wales have created: a tiny wire that doesn't even use electrons to carry a current.   view more (2006-07-26)

NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon.   view more (2007-07-17)

Dartmouth researchers discover chromium's hidden magnetic talents
Two Dartmouth researchers have determined that the element chromium displays electrical properties of magnets in surprising ways.   view more (2008-04-17)

University of Cincinnati researchers create all-electric spintronics
A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means.   view more (2009-10-28)

Nano-signals get a boost from magnetic spin waves
Researchers have figured out how nanoscale microwave transmitters gain greater signal power than the sum of their parts-a finding that will help in the design of nano-oscillator arrays for possible use as transmitters and receivers in cell phones, radar systems, or computer chips.   view more (2006-09-01)

Ohio University Researchers Create Improved Magnetic-Semiconductor Sandwich
Researchers at Ohio University have created an improved magnetic semiconductor that solves a problem spintronics scientists have been investigating for years.    view more (2006-10-03)

Toward a quantum computer, one dot at a time
Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots.   view more (2006-01-20)
