We are developing magnetic neutron waveguides (NWG) consisting of thin films of low-optical index sandwiched between two layers of high-optical index. In such structures, the neutron wave function is strongly localized in the guiding layer and the sensitivity to interface scattering effects is enhanced. The samples were characterized on the reflectometer HADAS (FZ Jülich, Germany) by specular reflectivity and off-specular scattering for different magnetic states of the permalloy layers. We show that the waveguide structure strongly enhances the off-specular scattering.
