Description

We propose the waveguides structures which transform an incident unpolarized neutron beam into a polarized microbeam and can also be used as spin-flippers by varying the incidence angle on the structure. We describe optimized structures combining these functions. Such waveguides could be used for the investigation of one-dimensional magnetic structures and implemented on any existing fixed wavelength reflectometer
