Abstract

Polarized neutron diffraction in multilayers is considered in the framework of the Supermatrix formulation of the distorted wave born approximation (DWBA). The general equations for the polarized neutron scattering cross sections are derived and illustrated by the example of diffraction from the regular ferromagnetic multilayered structure. It is shown that, due to the resonance enhancement of the neutron wave field inside the films, the intensity of birefrigent spin-flip and non-spin-flip diffraction is significantly amplified, if the wavelength is matched with the multilayers period.
