Schematic dispersion relations of spin waves propagating in 750 nm (left) and 1,000 nm (right) waveguides with implantation doses of 2.5 pC m −2 and 10 pC m −2 . At frequency f ex a spin wave can be excited in the narrow 750 nm waveguide formed with implantation doses of 2.5 pC m −2 (left). However, for the wider 1,000 nm waveguide, no mode exists at this frequency (stop band). By changing the implantation to a higher dose, the stop band can be tuned to compensate for dimensional changes and match the wavevectors k 1 and k 2 .
