Abstract
A device that produces spin waves includes a base substrate, a transducer that includes a first plane defined by a first magnetic film and a second plane defined by a plurality of metal strips, and a second magnetic film having a spin-wave phase velocity lower than the first magnetic film. The second magnetic film is adjacent to the first magnetic film, and the first plane and the second plane are parallel. The plurality of metal strips are configured to receive a first signal, such that the first signal excites a first spin wave in the first magnetic film. The second magnetic film is configured to produce a second spin wave having a wavelength shorter than the first spin wave.
