dc.descriptionFunding Information: This work was supported by the Academy of Finland (Grant Nos. 317918, 325480, and 338748). Lithography and FIB milling were performed at the OtaNano-Micronova Nanofabrication Center and the OtaNano-NanoMicroscopy Center, respectively, supported by Aalto University. Computational resources were provided by the Aalto Science-IT project. We thank Helmholtz-Zentrum Berlin for the allocation of synchrotron radiation beamtime.
dc.description.abstractWe report the imaging of short-wavelength spin waves in a continuous nanometer-thick YIG film with a Co stripe patterned on top. Dynamic dipolar coupling between the YIG film and the Co stripe lowers the spin-wave wavelength when spin waves enter the YIG/Co bilayer region from the bare YIG film, causing partial reflection at the YIG/Co edge. We use time-resolved scanning transmission x-ray microscopy to image the mode conversion process down to a wavelength of 280 nm and extract the spin-wave dispersion, decay length, and magnetic damping in the YIG/Co bilayer. We also analyze spin-wave reflection from the YIG/Co edge and its dependence on the wavelength of incoming and transmitted spin waves.en
