‘Spintronics, also known as magnetoelectronics, is an emerging technology that harnesses the spin of particles.
Conventional electronics ignores these rotations and instead exploits the movement or accumulation of electrons to do useful calculations or store data.
Freescale MRAM chip
Spintronics is already used in MRAM devices produced by Freescale
The movement of electrons through the tiny wires found in modern microchips is the reason why laptops become so hot.
But, by harnessing the twist and turns of particles – detected as a weak magnetic force – scientists hope to unlock almost infinite computing power and storage, without the heat.’
