Spintronics-Info: the spintronics experts

Spintronics-Info is a news hub and knowledge center born out of keen interest in spintronic technologies.

Spintronics is the new science of computers and memory chips that are based on electron spin rather than (or in addition to) the charge (used in electronics). Spintronics is an exciting field that holds promise to build faster and more efficient computers and other devices.

Researchers demonstrate that topological insulators are suitable for Spintronics applications

May 01, 2016

Researchers from the Helmholtz-Zentrum demonstrated that topological insulators are suitable for Spintronics applications. The researchers showed how the spins of the electrons in topological insulators can be controlled.

Characteristic spin orientation of electrons in a topological insulator

The researchers used circularly-polarized laser to investigate samples of antimony-telluride, a topological insulator. Using the rotational direction of the laser, it is possible to initiate and direct spin-polarised current. The researchers also succeeded to change the orientation of the spins.

£2.7 million granted for superconducting spintronics devices R&D

Apr 17, 2016

The UK's Engineering and Physical Sciences Research Council is funding a £2.7 million spintronics project led by the University of Cambridge. The aim of the project is to develop prototype superconducting spintronics devices for power-efficient supercomputing applications.

This work continues from the discovery of spin polarized supercurrents in 2010 at the University of Cambridge, as well as recent research that shows it is possible to power spintronic devices with a superconductor.

New Spintronics book: Nanomagnetic and Spintronic Devices for Energy-Efficient Memory and Computing

This book explores the recent and on-going research into nanomagnetic-based technology. The book gives a detailed background material and comprehensive descriptions of the current state-of-the-art research on each topic, while focusing on direct applications to devices that have potential to replace CMOS devices for computing applications such as memory, logic and higher order information processing.

The book also discusses spin-based devices and describes magnet switching methodologies to minimize energy dissipation.

The spin properties of light could enable spintronics and photonics to co-exist in devices

Mar 31, 2016

Researchers at Purdue University have shown that there is a very simple rule that governs light spin and momentum locking. This is a universal property for all optical materials and nanostructures, which makes it potentially very useful for photonic devices. This universality is unique to light and does not occur for electrons.

Light spin-momentum locking

The researchers aim to use these spin properties of light to interface with spintronics so that we might use both photons and electrons in devices.

Perfect zigzag-edged graphene ribbons highly attractive for Spintronics applications?

Mar 30, 2016

Researchers have succeeded, for the first time, in producing graphene nanoribbons (GNRs) with perfect zigzag edges. Electrons on these zigzag edges exhibit different (and coupled) rotational spin - which means they could be highly attractive for next-gen Spintronics devices.

In their work, the research team describes how it managed to synthesize GNRs with perfectly zigzagged edges using suitable carbon precursor molecules and a perfected manufacturing process. The zigzags followed a very specific geometry along the longitudinal axis of the ribbons.

Intel: we'll have to adopt fundamentally new transistor technologies in 4-5 years, Spintronics is a leading candidate

Feb 05, 2016

Intel's technology and manufacturing group leader, William Holt, says that if Intel wants to keep improving its chips, it will soon have to start using fundamentally new technologies. The company does not know which technology will be adopted, but there are two possible candidates at this stage - Spintronics, and tunneling transistors.

William says that the new technologies will have to be commercialized in four to five years (when Intel moves over to 7-nm production, which is thought to be the limit of silicon transistors), and will initially be used alongside silicon transistors. Intel says we'll need to stop expecting chips to be faster - as the new technologies will mostly benefit the energy efficiency rather than the speed of Intel's future chips.
