Flatté and his team report that a steady
magnon current introduced into one iron magnetic layer will produce a
magnon current in a second layer — in the same plane of the layer but at an angle to the introduced current.

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.
In contrast to electrical
currents, on which todays information technology is based,
magnon spin
currents do not conduct electrical charges but magnetic momenta.
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 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.
By means of the oscillating magnetic fields of irradiated microwaves the deliberate rotation of the YIG magnetization is induced, which emits a
magnon spin
current into the CoO.
This novel behavior of topological
magnon insulators could lead to new applications in such fields as spintronics, where spin
currents (rather than charge
current in electronics) could be exploited for energy - efficient technologies and information storage.
«Thus, we transport spin - angular - momentum from
magnons to electrons, and this transport leads to ultrafast spin
current,» Choi added.
