  We present a theoretical investigation of the polarization plane rotation at
light transmission - Faraday effect, through one-dimensional multilayered
magneto-photonic systems consisting of periodically distributed magnetic and
dielectric layers. We calculate Faraday rotation spectra of photonic-magnonic
crystals, where cell (or supercell) is composed of magnetic layer and
dielectric layer (or section of dielectric photonic crystal). We found that the
Faraday rotation of p-polarized incident light is increasing in the
transmission band with the number of magnetic supercells. The increase of
Faraday rotation is observed also in vicinity of the band-gap modes localized
in magnetic layers but the maximal polarization plane rotation angles are
reached at minimal transmittivity. We show that presence of linear
magneto-electric interaction in the magnetic layers leads to significant
increase of the Faraday rotation angles of s-polarized incident light in the
vicinity of the fine-structured modes inside the photonic-band-gap.
