    I believe spintronics is the future for most if not all far future micro-electronics for classical computers as spintronics promises to make classical computers not only much faster but THOUSANDS of times more energy efficient.

    This is a study that explains and demonstrates how detection of the electron spins for in spintronic circuitry using electric fields rather than magnetic fields is probably the best strategy for future spintronics.
    I believe this research result is a huge breakthrough and perhaps the biggest breakthrough in spintronic research yet and represents a very significant step toward realizing real-world application of spintronics.
    The link says;
    "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.

    and, for the first time, they demonstrated all-electrical spin-to-charge conversion without the need for a magnetic field.

    the link also says;
    "We showed that non-linear spin-to-charge conversion is fully consistent with the data obtained from linear response measurements and is orders of magnitude faster," ...
    Because the non-linear method does not need a magnetic field nor a long spin diffusion length, it promises new possibilities for fast detection of spin accumulation ...

    Finally, the rapidness of non-linear spin-to-charge conversion can enable time-resolved read-out of spin accumulation down to 1 nanosecond resolution.
    So it appears they are also saying this could result in much MUCH faster computations in the resulting spintronic micro-circuits; Overall a hugely significant result indeed!
