Query: The Faraday effect in magnetoplasmonic nanostructures with spatial
  modulation of magnetization   The magneto-optical Faraday effect in the magnetoplasmonic nanostructures
with nonuniform, periodically modulated spatial distribution of the
magnetization is considered. It is shown that in such nanostructures the
Faraday effect can experience the resonant enhancement in the spectral range of
the plasmonic and waveguide optical modes excitation. It happens both for $s$
and $p$-polarized light. Such an effect can serve for the spectrally selective
detection of the short spin waves in the magnetic materials.
