ELECTRON spin may be the solution computer-chip makers have been looking for
in their struggle to squeeze ever smaller and faster devices onto their
chips.
Exploiting the intrinsic “spin” of electrons will provide a wealth of
possibilities, and scientists have taken a key step in this direction,
developing a battery that can store electron spin and release it on demand.
Today’s electronic devices work by shuffling packets of electric charge
around a semiconductor circuit, in the form of groups of electrons. But
electrons also spin, giving them a magnetic field like a tiny bar magnet.
If you align the spin…
