Abstract

General equations for spin-flip and non-spin-flip specular reflection and off-specular scattering are analyzed for the case of multidomain states of magnetic multilayers. The results are illustrated by numerical calculations performed for Fe/Cr multilayers using an original software developed on the basis of the supermatrix formalism. This routine allows to calculate the reflectivities and scattering cross sections from the layered structures of any complexity for any directions of the incident polarization vector and directions of the polarization analysis.
