New theory could change the design of future spintronic circuits

The flow of electric charge lies at the heart of electronic circuits. However, electrons also have spin, and flows of electron spin play a vital role in spintronic circuits. These could be essential for our future computing ...

Double layer of graphene helps to control spin currents

In order to make transistors that operate using the spin of electrons rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be ...

Spin devices rev up

Electric currents drive all our electronic devices. The emerging field of spintronics looks to replace electric currents with what are known as spin currents. Researchers from the University of Tokyo have made a breakthrough ...

Toward ultrafast spintronics

Electronics have advanced through continuous improvements in microprocessor technology since the 1960s. However, this process of refinement is projected to stall in the near future due to constraints imposed by the laws of ...

Graphene bilayer provides efficient transport and control of spins

University of Groningen physicists in collaboration with a theoretical physics group from Universität Regensburg have built an optimized bilayer graphene device that displays both long spin lifetimes and electrically controllable ...

Zero field switching (ZFS) effect in a nanomagnetic device

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron ...
