Аннотация:A kinematical approximation has been derived from the general formulas for calculating the
reflectivity from a multilayer anisotropic structure. An explicit form of reflection matrices at the boundary of layers and the refraction tensors has been obtained for a particular case where the layer magnetization is ori ented in the surface plane and for an arbitrary form of X-ray susceptibility tensors. Calculations of the reflec tivity from a Nb(4 nm)/[Dy(5 nm)/Lu(3 nm)]420 model structure with helicoidal ordering of Dy magnetic layers show that kinematical approximation can be applied for grazing angles that are larger than the critical total reflection angle and that the “magnetic” refraction must be taken into account.
