Nanostructure and multifunctional properties of magneto-plasmonic materials

In this presentation I will illustrate how the particular nanostructural, compositional and electronic properties of two class of MP nanostructures determine the collective magnetic, magneto-optic and plasmonic properties. First the nanostructural features and properties of Au/Co/Au trilayers in which interface and the substrate determine their magneto-polariton properties will be shown. Second the plasmonic, magneto-optical and plasmonic properties of Au and Fe oxide nanoparticles with core@shell and heterodimers morphologies will be presented and discussed considering the particular growth. Spin polarization of the plasmon component is observed, illustrating the possibility of developing spin-plasmon devices.
