High magneto-optical activity and low optical losses in metal-dielectric Au/Co/Au-SiO 2 magnetoplasmonic nanodisks

Metal-dielectric Au-Co-SiO 2 magnetoplasmonic nanodisks are found to exhibit large magneto-optical activity and low optical losses. The internal architecture of the nanodisks is such that, in resonant conditions, the electromagnetic field undertakes a particular spatial distribution. This makes it p...

Sumario:Metal-dielectric Au-Co-SiO 2 magnetoplasmonic nanodisks are found to exhibit large magneto-optical activity and low optical losses. The internal architecture of the nanodisks is such that, in resonant conditions, the electromagnetic field undertakes a particular spatial distribution. This makes it possible to maximize the electromagnetic field at the magneto-optically active layers and minimize it in the other, optically lossy ones. Copyright © 2012 WILEY-VCH Verlag GmbH and Co.
