We present correlated experimental and theoretical studies on the magnetic field modulation of Surface Plasmon Polaritons (SPPs) in Au/Co/Au trilayers. The trilayers were grown by sputter deposition on glass slides with the Co films placed at different distances from the surface and with different thickness. We show that it is possible to tailor Au/Co/Au(More)
Plasmonic materials (PMs), featuring large static or dynamic tunability, have significant impact on the optical properties due to their potential for applications in transformation optics, telecommunications, energy, and biomedical areas. Among PMs, the carrier concentration and mobility are two tunable parameters, which control the plasma frequency of a(More)

The propagation of surface plasmon polaritons (SPPs) on gratings can be experimentally modified when magneto-optically active materials are used. We have observed this effect in Au-Co thin-film bilayers where a polymer grating was patterned on the upper surface. In addition, Au-Co-Au trilayers were grown on polycarbonate gratings, and the Co layer(More)
Modification of chemical order in epitaxial FePt binary alloy thin films deposited on MgO 100 substrates was induced and investigated in real time using x-ray rapid thermal annealing XRTA . This is possible because synchrotron undulator radiation has sufficient power density to induce significant structural modifications in thin films and its energy can be(More)
Technological advances in sensor designs (e.g. increased sensitivity) may be achieved by combining plasmonic and magneto-optical materials, thus leading to magneto-plasmonic systems. Noble metal-ferromagnetic systems, such as Au/Co/Au trilayers and Au/FePd bilayers, are candidates for magneto-plasmonic systems, where surface plasmon polaritons (SPPs) may be(More)

We fabricated one-dimensional periodic multilayered metamaterial structures consisting of Ag and SiO₂alternating layers. Optical responses, such as transmission and absorption, are consistent well within finite difference time domain (FDTD) simulations. Angle dependent real and imaginary dielectric permittivity reflection spectra demonstrate their(More)
