Conventional magnonics, though, uses magnetostatic spin waves that are difficult to propagate in complex nanoscale geometries. This study uses topologically protected edge spin waves to neatly address the issue. The suggested paradigm for designing robust, reconfigurable, on-chip magnonic devices like diodes, beam splitters, and interferometers could have quite an impact on engineering solutions in information technology.
