Grazing-incidence X-ray diffraction in crystals with magnetic amorphous film

Grazing-incidence diffraction on crystals with an amorphous magnetic layer is considered. It is shown that even far from the absorption lines, when the difference between the refractive indices for the waves with different polarizations is small, this diffraction geometry can be effectively used for the investigation of thin magnetic films. The effect of the excitatio of waves with orthogonal polarization is analyzed when a wave with the eigen-polarization is incident on the surface of the magnetic film. Results of numerical calculations are given for X-ray diffraction on a germanium single crystal with an amorphous magnetic layer. [Russian Text Ignored].
