In the metallic Co layer the magnon spin current gets converted into a charge current due to the so - called inverse spin Hall effect and is thus detected.
In the emerging field of magnon spintronics, researchers investigate the possibility to transport and process information by means of so - called magnon spin currents.
In contrast to electrical currents, on which todays information technology is based, magnon spin currents do not conduct electrical charges but magnetic momenta.

Not exact matches
The properties of individual magnons have not been studied at low temperatures corresponding to the «quantum limit» where all thermally - induced spin fluctuations vanish.
One fundamental building block of magnon spintronics is magnon logic, which, for instance, allows to perform logic operations and thus information processing by the superposition of spin currents.
