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 thin-film Fe3O4 is a promising candidate for flexible spintronics

Nov 22, 2016

Researchers from National Chiao Tung University (NCTU) demonstrated that it is feasible to grow an epitaxial Fe3O4 film on a flexible muscovite. The thin film was characterized by several methods and found preserve the electrical and magnetic properties of Fe3O4. The researchers performed bending tests to confirm that the heterostructures retain the physical properties under repeated cycles. 

The researchers conclude their paper, saying that the material is a promising candidate for flexible spintronics devices, based on the tunneling magnetoresistance on the flexible muscovite.

A lateral electric field can control the spin polarization in zigzag graphene ribbons

Nov 16, 2016

Researchers from Grennole Alpes University in France have demonstrated using atomistic calculations that a lateral electric field can be used to tune the carrier mobility and change the spin polarization of the current driving through zigzag graphene ribbons. The researchers say that these effects can be nicely exploited in spintronics devices.

The calculations predict a high variation of the carrier mobility, mean free path and spin polarization in the ZGNRs. It turns out that configurations with almost 100% spin-polarized current can be switched on and off.

Researcher manufacture high quality tungsten disulfide with strong spin-orbit coupling

Nov 16, 2016

Researchers from New York University developed a new a new manufacturing process for tungsten disulfide that resulted in highest quality ever reported for the material. The process is based on chemical vapor deposition (CVD), with some "subtle yet critical" changes.

The high-quality material provided a large energy bandgap and its charge carriers had a small effective mass. The material also exhibited strong spin-orbit coupling, which means that it may be an interesting material for spintronics.

Multiferroic Rashba semiconductors - a new promising spintronics material class

Oct 23, 2016

Researchers from EPFL and PSI discovered a new material class, which they term multiferroic Rashba semiconductors, that have promising spintronics properties.

The researchers started with a study on the electronic and spin structure of a material made of thin films of Germanium and Tellurium (GeTe) doped with Manganese (Mn). Using photoemission, the researchers were able to study these materials for the first time. It was found that the combination of spin-orbit interaction and magnetism produces some exotic properties.

JGU establishes a new spintronics junior research group

Oct 13, 2016

The Johannes Gutenberg University Mainz (JGU), with funding from the German Research Foundation (DFG), is setting up an Emmy Noether independent junior research group to study spintronics.

Skyrmions generated by hairy balls image

Specifically, the TWIST (Topological Whirls in SpinTronics) work group will study skyrmions - magnetic "particles" or nodes within a magnetic texture. Skyrmions are more stable than other magnetic structures and react particularly readily to spin currents - which makes them interesting for spintronics applications.

New spintronics book: Graphene in Spintronics: Fundamentals and Applications

This book aims to explain various issues of spin transport in graphene in detail, from both basic and technical points of view, and gives us a theoretical background for understanding spintronics behaviors in graphene.

The authors say that the book gives hints to overcome the the difficulties in graphene applications in the field of spintronics by comparing the physical properties of graphene and magnetoresistive (MR) phenomena in spintronics.
