We report on how a neutron grating interferometer can yield projection images of the internal domain structure in bulk ferromagnetic samples. The image contrast relies on the ultrasmall angle scattering of unpolarized neutrons at domain wall structures in the specimen. The results show the basic domains of (110)-oriented sheets in an FeSi test sample. The obtained domain structures could be correlated with surface sensitive magneto-optical Kerr effect micrographs.

  20. 20. The (110)-oriented FeSi (Fe3wt%Si) disk had a thickness of 300μm and was cut from a Goss-oriented transformer steel with a diameter of 10 mm. We note that surface polishing was only necessary to acquire the Kerr images; neutron DFI contrast can equally well be obtained on unpolished samples. Google Scholar

  22. 22. The images were recorded using a 100μm thick Li-6/ZnS converter and fluorescence screen with a 1:1 optical lens system and a cooled charge coupled device (Fingerlake Instrumentation) (1024×1024pixels, pixel size of 24×24μm2). The effective spatial resolution was mainly determined by the intrinsic blurring in the scintillation screen to 100μm (Ref. 21). A typical exposure time for a single raw image was 30 s; typically four or eight images were taken to yield one DCI. Google Scholar
