IBM is all set to publish a paper in Nature, a scientific journal, about the success of its spintronics memory. This memory product works on the principle of the natural spin of electronics inside a magnetic field. Among its deliverables are better capacity and lower energy use. Spintronics has faced limitation due to the fact that electrons have only an up or a down direction for 100 picoseconds. IBM states that it has found a way to sync the electrons in such a way so as to increase their spin lifetime to 1.1 nanoseconds. This is the time taken by a 1 GHz processor to cycle.
The scientists at IBM have achieved this result by using short laser pulses to look at the evolution of several thousand electron spins. Gallium arsenide is the material that has been used by the IBM researchers.
This material has served as their primary semiconductor material. Interestingly many other parties are also working on spintronics and the Institute of Materials Physics and Chemistry in Strasbourg is one of them.
