Instead of using electrical signals, spintronics uses magnetic signals to transmit data: processing becomes much more efficient in this way. The limiting problem is that magnetism is not so easily controlled, especially on a small scale. The waves propagate very quickly and disappear within nanoseconds.
A tamer of magnetic waves
It is in order to study these rapid oscillations that researchers from Delft University of Technology developed this tiny device.
In the space of just 11 atoms, the device has everything needed to detect, read and record data. The central idea of the invention is that the device instantly detects a magnetic wave and records this information.
Sander Otte, at the head of the research, compare the sensor to a mouse trap. “A mouse is too small and too quick to be caught by hand. But a mousetrap reacts faster, and succeeds. "
Research on the "atomic" sensor
The researchers connected the device to a magnetic wire made up of atoms, and sent magnetic waves through the "wire". Although the test wires were very short, the results are promising: the waves moved in a very peculiar way, as one would expect from quantum mechanics.
The next step is to apply this technique also to more complicated sensors and circuits to obtain more information on the behavior of spintronics.
