The birth of topological spintronics: New material combo could lead to more efficient computers

Posted: 23 Jul 2014 11:17 AM PDT

The discovery of a new material combination that could lead to a more efficient approach to computer memory and logic is the first promising indication that it may be possible to build a practical technology with a novel material known as a 'topological insulator.' The research team's results show that such a scheme can be 10 times more efficient for controlling magnetic memory or logic than any other combination of materials measured to date.
