GRAZING-INCIDENCE X-RAY-DIFFRACTION IN CRYSTALS WITH MAGNETIC AMORPHOUS FILM

Grazing-incidence diffraction on crystals with an amorphous magnetic l ayer is considered. It is shown that even far from the absorption line s, when the difference between the refractive indices for the waves wi th different polarizations is small, this diffraction geometry can be effectively used for the investigation of thin magnetic films. The eff ect of the excitation of waves with orthogonal polarization is analyze d when a wave with the eigen-polarization is incident on the surface o f the magnetic film. Results of numerical calculations are given for X -ray diffraction on a germanium single crystal with an amorphous magne tic layer.
