金属-介质Au-Co-SiO2磁等离子体纳米盘具有很高的磁光活性和很低的光损耗。纳米盘的内部结构使得在谐振条件下，电磁场呈现特定的空间分布。这使得可以最大化磁光有源层处的电磁场，并最小化其他光学损耗层中的电磁场。版权所有© 2012 WILEY-VCH Verlag GmbH and Co. KGaA，魏因海姆。
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.
