- New clues to mechanism for 'colossal resistance' effects
08-17-2007 · EurekAlert!
Experiments at the US Department of Energy's Brookhaven National Laboratory, shed new light on some materials' ability to dramatically change their electrical resistance in the presence of an external magnetic or electric field. Small changes in resistance underlie many electronic devices, including some computer data storage systems. Understanding and applying dramatic resistance changes, known as colossal magnetoresistance, offers tremendous opportunities for the development of new technologies, including data-storage devices with increased data density and reduced power requirements.

- Using a magnet to tune a magnet
08-01-2007 · EurekAlert!
An international research team, led by scientists at the London Centre for Nanotechnology, has found a way to switch a material's magnetic properties from "hard" to "soft" and back again -- something which could lead to new ways of controlling electromagnetic devices. The research will appear in the journal Nature on Aug. 2, and shows how a magnet can be "tuned" by subjecting it to a second magnetic field, perpendicular to the original.

- NRL generates, modulates, and electrically detects pure spin currents in silicon
12-03-2007 · EurekAlert!
NRL 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 enabling step for developing devices which rely on electron spin rather than electron charge, an emergent field known as "semiconductor spintronics." Progress in this field is expected to lead to devices which provide higher performance with lower power consumption and heat dissipation.

- Storing data on atomic roundabouts
10-10-2007 · EurekAlert!
Scientists at the University of Bonn have demonstrated the existence of right-handed and left-handed "magnetic vortices". Through their research, in collaboration with colleagues from Berlin and Geneva, they believe that this physical phenomenon could eventually lead to the construction of faster and more reliable hard-disks. The physicists have reported their discovery in the latest issue of the journal Nature.

- Beyond batteries: Storing power in a sheet of paper
08-13-2007 · EurekAlert!
Rensselaer Polytechnic Institute researchers have developed a new energy storage device that could be mistaken for a simple sheet of paper. The nanoengineered battery is lightweight, flexible and geared toward meeting the design requirements of tomorrow's electronics and implantable medical equipment. The device withstands extreme temperatures, is completely integrated, can be printed like paper, and can function as both a battery and a supercapacitor. It can also be partly powered by human blood or sweat.
