Researchers develop a way to inject an ultra-fast pulse of spin current

Researchers NTU, NUS, A*STAR and the Los Alamos National Lab have demonstrated that it is possible to inject an ultra-short pulse of spin current (less than a picosecond) from a metal to a semiconductor in a very efficient way.

Ultra-short laser pulses on cobalt - spin polarization photo

The researchers used a short laser pulse on cobalt (a magnetic material) - which generated a spin-polarized "swarm" of excited electrons. The spin-polarized electrons travel outside of the material - into adjacent materials. This creates an extremely efficient spin injection.

EU researchers fabricated graphene-based spintronics devices that utilize both electron charge and spin at room temperature

EU's Graphene Flagship project researchers fabricated graphene-based spintronics devices that utilize both electron charge and spin at room temperature.

The researchers demonstrated the spin’s feasibility for bridging distances of up to several micrometres - which they say could open the door to single-chip devices that integrate logic and memory.

A new guide to promising perovskite materials: The Perovskite Handbook

The Spintronics-Info team takes pleasure in recommending our new book - The Perovskite Handbook. This book gives a comprehensive introduction to perovskite materials, applications and industry. Perovskites offer a myriad of exciting properties and has great potential for several industry -including the spintronics one.

The Perovskite Handbook

We believe that any spintronics professional would find that perovskite materials are an area of focus that should not be ignored. The promising perovskite industry is currently at a tipping point and on the verge of mass adoption and commercialization and the first display-related perovskites are already reaching the market.

Perovskites are promising as spintronic materials, researchers develop two new perovskite spintronics devices

Researchers from the University of Utah developed two spintronics devices based on perovskite materials. The researchers use these new devices to demonstrate the high potential of perovksites for spintronics systems. This is a followup to the exciting results announced in 2017 by the same group that showed advantages of perovskites for spintronics.

The researchers use an organic-inorganic hybrid perovskite material that has a heavy lead atom that features strong spin-orbit coupling and a long injected spin lifetime.The first device is a spintronic LED which works with a magnetic electrode instead of an electron-hole electrode. The perovskite LED lights up with circularly polarized electroluminescence.

Researchers produce spin wave overtones in spintronic oscillators

Researchers from the University of Gothenburg have succeeded to produce spin wave overtones for the first time, which could enable faster wireless data communication based on spintronics devices.

Spintronic oscillators are devices in which spin waves are used to generate microwave signals in the gigahertz range. The new research shows how it is possible to produce spintronic oscillators that strengthen spin wave signals in several steps. This makes it possible to generate very high microwave frequencies with short wavelengths for use in spintronics and magnonics.
