This ability leads to some pretty clear advantages for magnonics, according to Fischer. Since it avoids electric currents, losses such as Joule heating can be drastically reduced. Also, spin waves can feature wavelengths in the nanometer-range and feature gigahertz frequencies, which allows for downscaling of devices and high-clock frequencies.
Nevertheless, there are still some challenges to be overcome such as the efficient excitation and detection of spin waves in order to couple magnonics to conventional electronics.
If it can be miniaturized...
