In this communication we present the results of theoretical investigation of Faraday and Goos-Haenchen (GH) effects in one-dimensional photonic-magnonic crystals (PMC) consisting of periodically distributed magnetic layers spaced by finite size dielectric photonic crystals. 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 studied the GH effect, i.e., the lateral shift of the light beam transmitted through PMC and show that the increase of the number of periods in the photonic-magnonic structure leads to increase of the GH shift in the vicinity of the frequencies of defect modes located inside the photonic band gaps. We also investigated an influence of the linear magnetoelectric coupling in the magnetic layers on the Faraday rotation and GH effect in PMC.
