Spin-filtering could be the key to faster, more energy-efficient switching in future spintronic technology, allowing the detection of spin by electrical rather than magnetic means.
A UNSW paper published last month demonstrates spin detection using a spin filter to separate spin orientation according to their energies.
Ultra-fast, ultra-low energy 'spintronic' devices are an exciting, beyond-CMOS technology.
The emerging field of spintronic devices use the extra degree of freedom offered by particles' quantum spin, in addition to its charge, allowing for ultra-fast, ultra-low energy computation.
The key is the ability to generate and detect spin as it accumulates on a material's surface.
The aim of researchers is to generate and detect spin via electrical means, rather than magnetic means, because electric fields are a lot less energetically costly to generate than magnetic fields.
Energy-efficient spintronics is dependent on both generation and detection of spin via electrical means.
In strongly spin-orbit coupled semiconductor systems, all-electrical generation of spin has already been successfully demonstrated.
However, detection of spin-to-charge conversion has always required a large range of magnetic fields, thus limiting the speed and practicality.
In this new study, UNSW researchers have exploited the non-linear interactions between spin accumulation and charge currents in gallium-arsenide holes, demonstrating all-electrical spin-to-charge conversion without the need for a magnetic field.

I don’t know about all that. I just put money in the machine and the clothes spin round till they’re dry.
That’s what I thought.
Whoa I thought that first word was ‘election’.
It would describe, after all, what the MSM has done with this election.
If only they could harness the color of quarks...
“The emerging field of spintronic devices use the extra degree of freedom offered by particles’ quantum spin, in addition to its charge, allowing for ultra-fast, ultra-low energy computation.”
I don’t know about that, but I know my head is spinning!
I’m off to copyright the term, “Spintronic”, just in case this takes off. Sounds like a name for a retro typewriter or something.
This should solve the dreaded stuck electron issue in the flux capacitor......
