摘要
The application of a neutron microbeam to the investigation of an internal magnetic microstructure has been demonstrated experimentally. The object of investigation is an amorphous magnetic wire 190 mu m in diameter, with the axial and circular magnetic domains formed inside it. A narrow neutron microbeam with a width of 2.6 mu m, which is formed by a three-layer film (a planar waveguide) serves as the probe for scanning with a high spatial resolution. The method of investigation is the neutron spin precession upon transmission through the sample.
