Our device consists of an array of nanomagnets on top of a continuous plasmonic film. The patterned nanomagnets magnetic state is single domain and well-defined shape anisotropy. Despite the presence of the patterned media on top of the Au film, the system exhibits surface plasmon resonance characteristics of a continuous film, i.e., propagating surface plasmon-polaritons.engjournal articlehttp://dx.doi.org/10.1364/OME.6.003086https://www.osapublishing.orgopen access538.9Magnetooptical activityMagnetoplasmonic crystalsShell nanoparticlesSurface-plasmonsFe oxideArraysCoreMediaFilmsFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
