A new kind of magnetism could unlock faster, more efficient computers - Science Daily

The computers of the future may rely on more than the electrical charge carried by electrons. Researchers are increasingly interested in another fundamental electron property called spin, which could provide a new way to move and process information inside electronic devices.

Conventional computers use the movement of electrical charge to handle data. If scientists can reliably control electron spin as well, they may be able to develop entirely new approaches to computing that operate faster and consume less energy.
