Abstract:We find that the Au-Co nanocomposite thin films grown at 300 ºC, which exhibit segregate nano-cluster microstructure and smooth surface capable of SPP propagation, exhibit largest magneto-optical effects than the films grown at lower and higher temperatures, as expected from our discussion on the correlation between SPR excitation and microstructure. We also note that the magneto-optical activity also increases with increasing Co concentration consistent with the presence of more magnetic material in the films, while the angular resolution of the field-dependent change of the reflectivity at resonance is somewhat insensitive to the amount of Co present. Our studies open up new possibilities for optimizing nano-composite materials that combine suitable properties, i.e. optical and magnetic, for applications that benefit from modulated sensing schemes, such as novel sensors based on SPR technology.
