Abstract

Multiresonant Au/Co/Au magnetoplasmonic nanorings exhibit magneto-optical (MO) activity that extends from the visible to the near infrared region. The spectral position and intensity of the MO features can be controlled by modifying the rings’ structural parameters, opening new routes for the design of systems with interest in sensing, optical communications and isolators.
