Magnetoplasmonics with plasmon nanoantennas — •Alexandre Dmitriev — Applied Physics, Chalmers University of Technology, 41296 Göteborg, Sweden

The combination of magnetism and plasmonics developed into a new burgeoning field, where the control of non-reciprocity in light's interaction with a magnetized media is targeted for various applications. I discuss the use of various ferromagnetic or hybrid noble metal-ferromagnetic plasmon nanoantennas to achieve broadband control of the magneto-optic response over the entire visible and near-infrared wavelength range. One example is the deployment of the magnetoplasmonic anisotropy to earn the broadband tunability of both the sign and amplitude of the Kerr rotation, crafting the manifold enhanced magneto-optical response of a chosen sign in spectral regions where the same ferromagnetic thin-film material shows the complete absence of naturally occurring magneto-optical Kerr effect. Another example is magnetoplasmonics-controlled circular dichroism.
