Description
We report the nonlinear spin-wave transport in the array of the ten and ninety 260 nm wide YIG nano-waveguides. A new method based on Ar+ ion beam etching was developed for the nano-waveguide fabrication using a positive CSAR resist as a hard mask. For generating and detecting spin waves, 2 µm wide microwave antennas spaced 5 µm apart are used. The propagating spin-wave spectroscopy is measured in Damon-Eshbach and backward volume configurations for different microwave powers to evaluate the efficiency of the nonlinear multimagnon scattering processes and compare it with the reference case of a continuous YIG film.
