Abstract
The surface layer of an epitaxial Fe/Cr multilayer system has been structured lithographically into stripes with 1
m period. Polarized neutron reflectometry and diffuse scattering under grazing incidence measurements show strongly enhanced domain formation compared to the unstructured sample. The domains are correlated throughout the layers. The lateral domain size is partly the period of the stripe pattern of the surface layer, and partly the double.

Fig. 2. SEM picture of the structured sample surface. The sample has been inclined by 60° around the horizontal axis of the picture, therefore the vertical distances are reduced to half.

Fig. 3. Reflectivity and diffuse scattering under grazing incidence. The scattered intensity (logarithmic colour scale) is plotted against incident angle and outgoing angle of the neutrons. The polarization channels are
R++ non-spin-flip with the neutron spin along the guiding field direction,
R−− non-spin-flip with the neutron spin opposite to the guiding field,
R+− and
R−+ spin-flip with the incident neutron spin parallel or antiparallel to the guiding field, respectively.
