The inverse Faraday effect is associated with light-induced magnetism. In nonmagnetic materials, the magnetic field scales with intensity; an electric field both produces surface charges and imparts momentum to those charges. The angular momentum of surface currents may induce a magnetic field, that is highly dependent on the shape nano-geometry. Here, we measure the Inverse Faraday Effect on nonmagnetic plasmonic nanodisks. We explore the effect of nanodisk aspect ratio. When the disk is thin, the plasmon resonance significantly red-shifts, which coincides with electron spillout.
