Researchers develop a nano-neuron based on a spintronics oscillator

Researchers from France, the US and Japan a spintronics-based oscillator that can mimic the behavior of neurons. A nano-neuron could be used to create new kind of chips that mimic the brain's computational style.

Spintronics oscillator vs Neuron image

The spintronics oscillator is a small cylinder composed of stacked magnets separated by an insulating, non-magnetic, barrier. This design enabled the fabrication of a nano-neuron that is capable of recognizing an input signal, which was in this case a spoken digit (0–9) pronounced by different speakers, with a success rate of 99.6%. This result is on a par with other state-of-the-art technologies.

Bismuthene is a newly developed graphene-like 2D topological insulator

Researchers from the University of Würzburg developed a new room-temperature 2D topological insulator material that is promising for spintronics applications.

To create this material, the researchers used a single-sheet of bismuth atomsdeposited on a silicon carbide substrate. The silicon carbide structures causes the bismuth atoms to arrange in a honeycomb structure - which resembles the structure of graphene films. The researchers call their new material "bismuthene".

As part of the research, it was demonstrated that the spin characteristics of graphene can be electrically regulated in a controlled way, even at an ambient temperature. This structure is not only useful to make spin-logic devices - it can also be used to integrate device-level magnetic memory (MRAM) elements.

Researchers manage to generate and manipulate the surface spin current in topological insulators

Researcherrs from Likoping University in Sweden demonstrated a method to generate and manipulate the surface spin current in topological insulators.

Transferring spin-oriented electrons (Linkoping)

The researchers used a combination of a topological insulator (Bismuth Telluride, Bi2Te3) and a regular GaAs semiconductor. The electrons were generated with the same spin in the GaAs using polarized light. The electrons were then transferred to the TI.
