Pin It

Spintronics is an emerging field of technology where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds with lower energy consumption. Spintronic circuits need ways to control electron spin without interference from electron charge. Scientists at Ecole Polytechnique Federale de Lausanne, working with Université Paris-Sud and Paul Scherrer Institut, have discovered that a common insulating material behaves as a perfect spintronic conductor because it is not affected by background electron charge. In addition, the material's properties make it an ideal platform for directly observing a strange subatomic particle that could one day lead to a different, more stable type of quantum computers.
