Faraday rotation images visualizing the spin-wave propagation. The superimposed optical transmission images indicate the implantation dose (greyscale). In c , dose 1 and dose 2 are equal (2.5 pC m −2 ), resulting in strongly suppressed spin-wave propagation in the wider (1,000 nm) waveguide and strong back reflections.
