Аннотация:Planar waveguides can transform a conventional neutron beam into a very narrow but slightly divergent microbeam. Such
microbeams could be used for the investigation of nanostructures with a high spatial resolution. We have investigated the
tri-layer magnetic structure Fe/Co/Fe which transforms an unpolarized incident beam into a polarized microbeam. The
polarized neutron reflectometer NREX with a horizontal sample plane was used for the waveguide characterization. Some
practical aspects of microbeam extraction and polarization are discussed.
