SEM image and Brillouin spectra of the Py/BARC magphonic crystal. (a) SEM image and schematics of the sample and scattering geometry employed, showing the orientation of the Cartesian coordinate system with respect to nanostripes and phonon/magnon wavevector q. Polarization Brillouin spectra of (b) phonons and (c) magnons. Lattice constant a = 350 nm.
