By Catherine Zandonella 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,
