Operation a spin-waveguide with memory elements

In this experimental study, we delve into the potential implementation of logic operations using the interference of propagating spin waves within a device comprising intersecting yttrium iron garnet waveguides with submicrometer width. Notably, we extend our exploration to incorporate phase-change materials as memory elements atop these waveguides. Our results underscore critical considerations in the design of magnonic nanodevices operating with short-wavelength spin waves, offering valuable insights for optimizing their performance in practical applications.
