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 develop a wavelength-selective plasmonic metamaterial absorber on top of a spintronic device

Oct 11, 2017

Researchers from Japan's National Institute for Materials Science have developed a wavelength-selective plasmonic metamaterial absorber (PMA) on top of a spintronic device. The researchers say that this design enhances the generation of spin currents from the heat produced in the mid-infrared regime.

The researchers used a mid-infrared plasmonic metamaterials, combined with a spintronics device for the first time. This unique combination enables stronger light absorption and shows the excellent tenability of these metamaterials' resonance wavelengths

Researchers show how to create spin-valley half-metals

Sep 17, 2017

Researchers from Russia and Japan have shown, theoretically, that it is possible to create a new class of materials: spin-valley half-metals. These kind of devices could enable both spintronics valleytronics applications.

In "regular" half-metals, all the electrons that participate in electric currents have the same spin - and so the current is always spin-polarized. These materials have interesting applications for spintronics devices. In the new class of materials now proven theoretically to be possible, there are two valleys present - one providing electrons, one providing holes.

New film material enables to control and detect magnetic skyrmions

Sep 06, 2017

Researchers from Singapore's A*STAR and NTU developed a tunable room-temperature platform that can be used to control and detect magnetic skyrmions. This platform is actually a thin film made from multi-layer stacks of Ir/Fe/Co/Pt.

In this material, the magnetic interactions governing skyrmion properties can be controlled by varying the ferromagnetic layer composition. The skyrmions exhibit a smooth crossover between isolated (metastable) and disordered lattice configurations across samples, while their size and density can be tuned by factors of two and ten, respectively.

Magnetic electrodes used to generate spin current from organic solar panels

Sep 01, 2017

Reserachers from Spain's CIC nanoGUNE and IKERBASQUE discovered that you can use organic solar panels to created spin-current. The researchers used cobalt and nickel-iron magnetic electrodes to create spin-polarized current from a solar panel made from C60 fullerenes.

The researchers created the device by evaporating the metal and the C60 fullerenes onto a substrate, replacing the usual indium tin oxide and aluminium electrodes.

EU-funded project announced the first prototypes of nanoporous magnetic memories

Aug 31, 2017

The partners in the EU-funded SPIN-PORICS (Merging Nanoporous Materials with Energy-Efficient Spintronics) announced the first prototypes of nanoporous magnetic memories, based on copper and nickel alloys (CuNi).

The project team reported being able to achieve a 35% reduction of magnetic coercivity compared to current devices, which meets the energy consumption required to reorientate the magnetic domains which is necessary for data recording. This result is due to the nanoporous design which enables the whole film - not only the surface - to participate in the electromagnetic effect.

New graphene manipulation may enhance its spintronics properties

Aug 30, 2017

Researchers at the U.S. Department of Energy’s Ames Laboratory were able to theoretically calculate the mechanism by which the electronic band structure of graphene could be modified with metal atoms.
