enhancement of the magneto-optical response [23, 34, 41, 42]. As a
consequence, a number of technological applications have appeared
in the last few years, including magnetoplasmonic optical switches
and modulators [43, 44], optical isolators [45], plasmonic circuits
[46], and magnetoplasmonic sensors [47].
In this chapter, special attention will be devoted to SPP mode
modulation in noble-ferromagnetic multilayers such as Au/Co/Au
using the prism coupler configuration, which allows for intense
SPP modes highly sensitive to external magnetic fields [21–23,
