Magnonic nano-fibers for future computers

02.07.2020

A critical advancement in the field of ultralow power computation using magnetic waves is reported by a joint team from Kaiserslautern, Jena and Vienna in the journal Nano Letters

Research groups specialized in magnonics, which utilizes magnons for the development of novel types of computers, potentially complementing the conventional electron-based processors used nowadays, have been able to develop a thin strip of Yttrium Iron Garnet (YIG) measuring 50 nanometers.


“We were able to prove experimentally that magnons can efficiently carry information over long distances in these nano-conduits as was predicted theoretically before“, comments Björn Heinz, a PhD student of Andrii Chumak at the TU Kaiserslautern and the lead author of the paper. 


This research supposes a new step towards computers using magnons, which could be more powerful and, most importantly, consume less energy than current ones.
